This process can be conveniently effected by contacting the appropriate starting material of Formula A, having the desired R, R.sup.1 and R.sup.2 substituents, with the appropriate secondary or primary amine of Formula B having the appropriate R.sup.3 and R.sup.4 substituents, preferably in an inert organic solvent and in the presence of a scavenger base. This process is typically conducted at temperatures in the range of about from 0.degree. to 80.degree. C. and preferably about from 20.degree. to 40.degree. C., for about from 1 to 24 hours and preferably about from 1 to 4 hours. Typically a mol ratio of the compound of Formula A to the compound of Formula B in the range of about from 1 to 2 mols of compound of Formula B per mol of compound of Formula A and preferably about from 1 to 1.2 mols of compounds of Formula B per mol of compound of Formula A is used. Best results are typically obtained by conducting the process at temperatures in the range of about from 20.degree. to 40.degree. C. for about 1 to 2 hours using about a 1:1 mol ratio of compound of Formula B to compound of Formula A. Also, as is readily apparent, the reaction gives off hydrogen chloride or hydrogen bromide as a by-product. Accordingly, it is preferable to conduct the reaction in the presence of a suitable scavenger base, e.g., triethylamine, which reacts with the hydrogen chloride or hydrogen bromide byproduct. Other scavenger bases which could be used, include, for example, pyridine, 2,6-butadine, and the like. Typically, and preferably, the process is conducted in an inert organic solvent. Suitable inert organic solvents which can be used, include, for example, acetonitrile, 1,2-dimethoxyethane, methylene chloride, and the like and compatible mixtures thereof. Also, as can be expected optimum conditions will vary somewhat with the particular substrates used and can be determined by routine experimentation.

The compound of Formula 1 can be recovered by any suitable separation and purification procedure, such as, for example, recrystallization, and chromatography. Suitable separation and purification procedures, are, for example, illustrated in the Examples set forth herein below.

The starting materials of Formula A are generally known compounds and can be prepared according to known procedures, or by obvious modifications of such procedures; for example by the substitution of appropriate substrates and solvents, etc. The compounds of Formula A can, for example, be prepared by reacting the corresponding unsubstituted imino of Formula A with the corresponding acetylhalide or propenylhalide to yield the corresponding compound of Formula A having a 1-hydroxyalkylhalide substituent. This compound can in turn be reacted with the desired vinylchloride or vinylbromide to yield the corresponding compound of Formula A having a chloro or bromide substituent respectively at the 1- position of the alkylimino substituent. This procedure is, for example, described in U.S. Pat. No. 3,925,553.

Also, if desired, the acid addition salts of the compounds of Formula 1 can be prepared by carefully neutralizing the amino moiety of the compound with the appropriate acid. Other addition salts can then be made from this salt by ion exchange with a suitable ion exchange resin having the desired anionic form. Also, if desired, the respective optical isomers can be obtained by conventional resolution procedures, for example, by reacting the isomer mixture with an optically active acid which will yield a mixture of optical salts, of the desired compound, which can be resolved by conventional procedures (e.g., crystallization) into the respective plus and minus optical salts. The geometric isomers, for example, where R.sup.2 is alkenyl, can be separated by conventional procedures.

It should also be appreciated that where typical preferred process conditions (e.g., reaction temperatures, times, mol ratios of reactants, solvents, etc.) have been given, that other process conditions could also be used, though typically with poor yields or economies.

The compounds of the invention exhibit substantial fungicidal activity against a variety of fungi, including rhizoctonia, helminthia, monilinia, bean rust, celery late blight, and botrytis. Thus, the compounds can be applied to such fungi or to hosts which are subject to attack from such fungi, such as soil, and plants of the general grass family. The compounds can also be applied to combat fungus in domestic and industrial environments. The optimum dosage will, of course, vary with the particular fungi, host, and environment, but typically will be in the range of about from 100 to 1000 ppm by weight based on the weight of active ingredient to solvent.

The compounds could be applied directly to combat fungi but conveniently and typically are applied as fungicidal formulations comprising the compound(s) of the invention with a biologically inert solid or liquid. Generally the fungicide formulation contains the compounds of invention in amounts ranging from 0.005 to 95% by weight and preferably about from 1 to 50% by weight. These formulations are generally concentrates designed for further dilution prior to application.

Typical of the liquid carrier which can be admixed with the imidazolidinediones of this invention include liquids such as acetone, water, kerosene, xylene, alcohols, alkylated naphthylene and glycols. Typical solids which can be incorporated with the present compound include the natural clays such as kaolin clays and diatomaceous earth, synthetic fine silica, talc, pyrophyllite, etc.

The fungicidal formulations can also contain stabilizers, spreading agents, sticking agents, fillers, other compatible fungicides and pesticides, and the like.

At higher concentrations the compounds of the invention also exhibit both pre-emergent and post-emergent herbicidal activity against a variety of broad-leaved weeds, including mustard, pigweed, and lambsquarter. At relatively high concentrations the compounds also have pre-emergent herbicidal activity against a variety of grasses. Thus, the compounds can be applied as herbicides either directly or more pragmatically can be applied in a herbicidal composition comprising the active compound in an inert carrier or diluent.

Such herbicidal compositions comprise from about 0.01 to 95% by weight of the herbicidal compounds of the invention, intimately admixed with a biologically inert liquid or solid carrier, e.g., powders, dusts or granules. Suitable liquid diluents which can be used include, for example, water, organic solvents (e.g., hydrocarbons such as benzene, toluene, kerosene, diesel fuel, fuel oil, petroleum naphtha, etc.) and the like. Suitable solid carriers which can be used include, for example, natural clays (such as kaolin, attalpulgite, montmorillonite, etc.), talcs, pyrophyllite, diatomaceous silica, synthetic fine silica, calcium aluminosilicate, tricalcium phosphate, and the like. Also, organic materials, such as, for example, walnut shell flour, cottonseed hulls, wheat flour, wood flour, wood bark flour, and the like can also be used as carriers. The herbicidal composition typically also contains a small amount of one or more surface-active agents such as wetting agents, dispersing agents and can also contain compatible insecticides and additional compatible herbicides. The surface-active agent can either be anion, cationic or nonionic in character. The herbicidal composition can also contain compatible pesticides and adjuvants, stabilizers, conditioners, fillers, and if desired, other herbicidally active compounds, and the like.

The herbicidal compounds or the herbicidal compositions of the invention can be applied by conventional procedures which are well known by the art. For example, where the herbicide is applied in a pre-emergent application, it is applied directly to the area of soil desired to be protected. For post-emergent application, the herbicidal compositions will be applied directly to the foliage or other plant parts. The optimum amount of the herbicidal compound or composition will vary with the particular plant species, and the extent of part plant growth and the particular part of the plant which is contacted. The optimum dosage will also vary with the general location, or environment, of application (e.g., sheltered areas such as greenhouses compared to exposed areas such as fields), and type and degree of control desired. Generally, for both pre- and post-emergent control, the herbicidal compounds are applied at rates of about from 0.2 to 60 kg/ha, preferably about from 0.5 to 10 kg/ha.

A further understanding of the invention can be had in the following non-limiting Examples. Wherein, unless expressly stated to the contrary, all temperatures and temperature ranges refer to the Centigrade system and the term "ambient" or "room temperature" refers to about 20.degree. C. The term "percent" or "%" refers to weight percent and the term "mol" or "mols" refers to gram mols. The term "equivalent" refers to a quantity of reagent equal in mols, to the mols of the preceding or succeeding reactant recited in that example in terms of finite mols or finite weight or volume. Also, unless expressly stated to the contrary, geometric isomer and racemic mixtures are used as starting materials and correspondingly isomer mixtures are obtained as products. Where given proton-magnetic resonance spectrum (p.m.r.) are determined at 60 mHz, and signals are assigned as singlets (s), broad singlets (bs), doublets (d), double doublets (dd), triplets (t), double triplets (dt), quartets (q) and multiplets (m).

This preparation illustrates the preparation of the starting materials of Formula A wherein R or R.sup.1 is 2-fluorophenyl.

In this preparation 1-(2-fluorophenyl)-3-methyl-5-imino-1,3-imidazoladine-2,4-dione (10.0 g-0.045 mol) was slurried in 80 ml of 1,2-dimethoxyethane. Chloral (13.4 g-0.090 mol) was added, followed by the addition of 10.8 g (0.090 mol) of thionyl chloride. The reaction mixture became homogeneous as the temperature rose from the heat of reaction. The temperature was maintained at 35.degree.-45.degree. C. for one-half hour. The solvent was then removed from the mixture and the residue taken up in benzene. Filtration removed some high-melting white solids. Hexane was added to precipitate the product, which was then recovered by filtration and washed with ether affording 1-(2-fluorophenyl)-3-methyl-5-(1,2,2,2-tetrachloroethyl)imino-1,3-diazolid ine-2,4-dione. The product melted at 175.degree.-177.degree. C. Elemental analysis showed: %C, calc. 37.2, found 37.5; %H, calc. 2.1, found 1.9; %N, calc. 10.9, found 10.9; %Cl, calc. 36.6, found 36.3.

Similarly, 1-(2-fluorophenyl)-3-methyl-5-(1,2,3,3,3-pentachloropropyl)imino-1,3-imida zolidine-2,4-dione is prepared by following the same procedure but replacing chloral with alpha,beta,beta,beta-tetrachloropropionic acid aldehyde (i.e., Cl.sub.3 CCHClCHO).

Similarly, 1-methyl-3-(2-fluorophenyl)-5-(1,2,2,2-tetrachloroethyl)imino-1,3-imidazol idine-2,4-dione and 1-methyl-3-(2-fluorophenyl)-5-(1,2,3,3,3-pentachloropropyl)imino-1,3-imida zolidine-2,4-dione are prepared by the above procedure by respectively replacing 1-(2-fluorophenyl)-3-methyl-5-imino-1,3-imidazolidine-2,4-dione with 1-methyl-3-(2-fluorophenyl)-3-methyl-5-imino-1,3-imidazolidine-2,4-dione.

This example illustrates the preparation of the starting materials of Formula A wherein R.sup.2 is haloethyl.

In this preparation 1-methyl-3-phenyl-5-imino-1,3-diazolidine-2,4-dione (10.15 g; 0.05 mol) was dissolved in 80 ml 1,2-dimethoxyethane. Chloral (13.7 g, 1.0 mol) was added followed by the addition of thionyl chloride (11.9 g, 1.0 mol). The temperature of the reaction mixture rose to 45.degree. C. due to the exothermicity of the reaction. One hour later the temperature was back to 23.degree. C. and a solid had formed. The solid (1.1 g) had a melting point 140-150 with some not melting at all. The filtrate was stripped to give 9.6 g of a crude material which was recrystallized from benzene and washed with ether to give 8.2 g (0.02 mol) of 1-methyl-3-phenyl-5-(1,2,2,2-tetrachloroethyl)imino-1,3-diazolidine-2,4-di one melting at 158.degree.-160.degree. C.

Elemental analysis showed: %C calc. 39.06 found 39.2; %H calc. 2.46 found 2.3; %N, calc. 11.39 found 11.4; %Cl calc. 38.43 found 38.5.

Similarly, 1-methyl-3-phenyl-5-(1,2,2,trichloro-3,3,3-tribromopropyl)imino-1,3-diazol idine-2,4-dione is prepared by following the same procedure but replacing chloral with beta,beta,beta,tribromo-alpha,alpha-dichloropropionic and aldehyde.

Similarly, 1-phenyl-3-methyl-5-(1,2,2,2-tetrachloroethyl)imino-1,3-imidazolidine-2,4- dione and 1-phenyl-3-methyl-5-(1,2,2-trichloro-3,3,3-tribromopropyl)imino-1,3-imidaz olidine-2,4-dione are prepared by the above procedure by respectively replacing 1-methyl-3-phenyl-5-imino-1,3-imidazolidine-2,4-dione with 1-phenyl-3-methyl-3-5-imino-1,3-imidazolidine-2,4-dione.

This example illustrates the preparation of the compounds of Formula 1 of the invention wherein R.sup.2 is a halomethyl.

In this example 1-(2-fluorophenyl)-3-methyl-5-(1,2,2,2-tetrachloroethyl)imino-1,3-diazolid ine-2,4-dione (7.75 g, 0.02 mol) was dissolved in 20 ml of acetonitrile, 2-fluoro aniline (2.2 g, 0.02 mol) was added. A mild exothermic reaction took place. After 10 minutes, triethylamine was added to the reaction mixture causing a very exothermic reaction to take place. Exothermicity subsided within the hour but stirring was continued for five hours. Ethyl ether (20 ml) was added to help precipitate the salts. The mixture was filtered and solvent was removed from the filtrate by high vacuum evaporation, thereby affording 1-(2-fluorophenyl)-3-methyl-5-(1-2'-fluorophenylamino-2,2,2-trichloroethyl )imino-1,3-diazolidine-2,4-dione identified its I.R. and p.m.r. spectera and the elemental analysis.

In this example 0.02 mol of 1-(3,5-dichlorophenyl)-3-methyl-5-(1,2,2,2-tetrachloroethyl)imino-1,3-diaz olidine-2,4-dione is dissolved in 20 ml of acetonitrile and then 0.02 of mol of 2,4-dichloroaniline is added. After about 10 minutes, triethylamine is added to nrutralize the byproduct HCl produced by the reaction. The mixture is stirred for five hours and 20 ml of ethyl ether is then added.

This example illustrates the herbicidal properties of the compounds of Formula 1.

Pre-emergence herbicidal activity was determined in the following manner.

An acetone solution of the imidazolidinedione test compound was prepared by mixing 750 mg of the test compound, 220 mg of a nonionic surfactant and 25 ml of acetone. This solution was added to approximately 125 ml of water containing 156 mg of surfactant.

Seeds of the test vegetation were planted in a pot of soil and the imidazolidinedione test solution was sprayed uniformly onto the soil surface at a dose of 100 mcgm/c.sup.2. The pot was watered and placed in a greenhouse. The pot was watered intermittently and was observed for seedling emergence, health of the emerging seedlings, etc., for a 3-week period. At the end of this period, the herbicidal effectiveness of the imidazolidinedione test compound was rated based on the physiological observations. A 0-to-100 scale was used, 0-representing no phytotoxicity and 100 representing complete kill. The results of these tests are summarized in Table 1, hereinbelow.

The test compound was formulated in the same manner as described above for the pre-emergent test. The concentration of the test compound in this formulation was 5000 ppm. This formulation was uniformly sprayed on 2 similar pots of 24-day-old plants (approximately 15 to 25 plants per pot) at a dose of 33 micrograms/cm.sup.2. After the plants had dried, they were placed in a greenhouse and then watered intermittently at their bases, as needed. The plants were observed periodically for phytotoxic effects and physiological and morphological responses to the treatment. After 3 weeks, the herbicidal effectiveness of the compound was rated based on these observations. A 0-to-100 scale was used, 0 representing no phytotoxicity and 100 representing complete kill. The results of these tests are summarized in Table II.

The compounds tested are identified in Table A and the results of these tests are summarized in Table 1 with respect to pre-emergent herbicidal activity and Table 2 with respect to post-emergent herbicidal activity.

As can be seen from the above Tables 1 and 2 the compounds of the invention generally exhibit good pre-emergence herbicidal activity against broad-leaf plants and at higher concentrations generally exhibit good pre-emergence herbicidal activity against grasses and post-emergence herbicidal activity against broad-leaf plants. However, the compounds exhibit virtually no post-emergence herbicidal activity against grasses. This lack of post-activity against grasses facilitates the use of these compounds as fungicides to treat or protect grasses infected with or subject to fungus attack.

In this example the fungicidal activity of the number of the compounds, of Formula A, were tested for effectiveness against spores of Monilina fructicola by means of a variation of "The Standard Spore Slide--Germination Method for Determining Fungicidal Activity", described in the "American Phytopathological Society Journal", Vol. 33, 627-632 (1943) unless otherwise indicated. This method measures the fungitoxic activity of fungicidal chemicals, their activity being expressed in terms of percent inhibition of germination of fungus spores. The compounds tested were dissolved in acetone to a concentration indicated in Table 3, hereinbelow. The solutions were pipetted into the wells of depression slides and allowed to dry. The wells were filled with a suspension of the fungus spores. The spores were then incubated in a moist chamber overnight. A group of 100 spores was examined and the number of spores germinated and not germinated was counted and recorded to show the biological activity in terms of the percent germination inhibition.

Activity against tomato early blight, Alternaria solani condidia was determined in the following manner. Tomato (v. Bonny Best) seedlings of 6 to 7 weeks old were used. The tomato plants were sprayed with a 100 ppm solution of the test compound in an acetone-and-water solution containing a small amount of a monionic emulsifier. The sprayed plants were inoculated one day later with the organism, dried and maintained at 60-80% relative humidity for about 12 days. Percent disease control was based on the percent disease development on untreated check plants.

The celery late blight tests were conducted using celery (Utah) plants 11 weeks old. The celery late blight organism was Septoria apii. The celery plants were sprayed with a 150 ppm solution of the test compound mixed in an acetone-and-water solution containing a small amount of a nonionic emulsifier. The plants were then inoculated with the organism and placed in an environmental chamber and incubated at 66.degree.-68.degree. F. in 100% relative humidity for an extended period of time (approximately 48 hours). Following the incubation the plants were allowed to dry and then were maintained at a 60-80% relative humidity for approximately 14 days. The percent disease control provided by a given test compound is based on the percent disease reduction relative to untreated check plants. The results are reported in Table 3.

The leaf rust test was made using pinto beans. The pathogen was Uronyces phaseoli tipica. The pinto bean plants were sprayed with a 250 ppm solution of the test compound in an acetone-water mixture containing a nonionic emulsifier. The treated plants were inoculated thereafter with the pathogen and then incubated in an environmental chamber of approximately 20 hours at 100% relative humidity and a temperature of 68.degree.-70.degree. F. The plants were then removed from the chamber, allowed to dry, and then maintained in a greenhouse at a 60-80% relative humidity. The rate of infection on the leaves was made after about 14 days. The percent disease control provided by a given test compoundf was based on the disease reduction relative to untreated check plants. The results are summarized in Table 3 hereinbelow.

(The compounds tested are identified in Table A of Example 8 hereinabove.)

As can be seen from Table 3, although the compounds of the invention do not exhibit broad spectrum fungicidal activity, they generally exhibit good activity against Rhizoctonia. The compound also generally exhibits moderate to strong fungicidal activity against Helminthia, tomato leaf blight, bean rust, celery leaf blight and in some instances systemic bean rust.

Obviously, many modifications and variations of the invention described hereinabove and below in the claims, can be made without departing from the essence and scope thereof.
