Insecticidal Bicyclooxyphenyl Ureas

This invention relates in general to novel bicyclooxyphenyl ureas. In one aspect, this invention relates to processes for the preparation of the bicyclooxyphenyl ureas. In a further aspect, the invention relates to pesticidal formulations containing the ureas as at least one of the active ingredients of such compositions. In a still further aspect, the invention is directed to the use of the compositions in controlling plant pests.

Prior to the present invention few benzoyl ureas had been reported in the patent literature as having pesticidal activity. For example, U.S. Pat. No. 3,992,553 which issued on Nov. 16, 1976, and U.S. Pat. No. 4,041,177 which issued on Aug. 9, 1977, both disclosed certain benzoylureido-diphenyl ethers which were indicated to possess insecticidal properties. Similarly, U.S. Pat. Nos. 3,748,356 and 3,933,908 also disclosed certain substituted benzoyl ureas and stated that the compositions had strong insecticidal activity. U.S. Pat. No. 4,148,902 which issued Apr. 10, 1979 discloses substituted ((phenylamino)carbonyl) pyridine carboxamides and claims a method of controlling insects in addition to the compositions themselves. However, prior to the present invention no bicyclooxyphenyl ureas, such as, bicyclooxyphenyl benzoyl ureas have been reported in the literature as being useful for the control of plant pests.

The bicyclooxyphenyl ureas of this invention can be conveniently represented by the following formula: ##STR1##

wherein M represents an monocyclic aromatic ring system or a monocyclic heterocyclic ring system containing up to 2 nitrogen atoms, and wherein the rings can contain up to four X substituents wherein each X individually can be halogen, nitro, cyano, or alkyl, polyhaloalkyl, alkoxy or polyhaloalkoxy of from 1 to 3 carbon atoms;

Z and Z.sup.1 individually are hydrogen or alkyl of from 1 to 8 carbon atoms, or alkyl of from 1 to 8 carbon atoms which is substituted with at least one of halogen, hydroxyl or alkoxy;

Y individually represents halogen, or alkyl, polyhaloalkyl, alkoxy or polyhaloalkoxy of from 1 to 3 carbon atoms, and n has a value of from 0 to 4;

B is a bicyclic fused ring system which is attached to the oxygen through a carbocyclic ring and wherein (a) at least one ring is a six-membered, unsaturated carbocyclic ring which can contain up to two R and R.sup.1 substituents wherein R and R.sup.1 can be halogen, nitro, cyano, amino, formamido, formamidino, phenylsulfenyl, phenylsulfinyl, phenylsulfonyl, phenylsulfamido, wherein the phenyl ring optionally may be substituted with one or more halogen, nitro, or alkyl, polyhaloalkyl, alkoxy or polyhaloalkoxy of from 1 to 3 carbon atoms, or R and R.sup.1 individually are alkyl, alkoxy, polyhaloalkyl, polyhaloalkoxy, alkenyloxy, polyhaloalkenyloxy, alkynyloxy, polyhaloalkynyloxy, alkylsulfenyl, polyhaloalkylsulfenyl, alkylsulfinyl, polyhaloalkylsulfinyl, alkylsulfonyl, polyhaloalkylsulfonyl, mono- or di-alkylsulfamido, mono- or di-alkylamino, alkylcarbonylamino, alkoxycarbonylamino, mono- or di-alkylaminocarbonyloxy of up to 6 carbon atoms and (b) the second ring, hereinafter also referred to as A, when it is not a five or six-membered carbocyclic can be a five or six-membered saturated or unsaturated heterocyclic ring which can contain in any combination carbonyl or one or two oxygen or sulfur, and up to two R.sup.2 and R.sup.3 substituents attached to unsaturated ring carbon atoms wherein R.sup.2 and R.sup.3 individually can be halogen, nitro, cyano, or alkyl, polyhaloalkyl, alkoxy, polyhaloalkoxy, alkylthio, arylthio, alkylsulfinyl, arylsulfinyl, alkylsulfonyl, arylsulfonyl, alkylsulfamido, arylsulfamido, alkoxycarbonylamino, or alkylcarbonylamino of from 1 to 6 carbon atoms, or the ring can contain up to two R.sup.4 and R.sup.5 substituents attached to saturated ring carbon atoms wherein R.sup. 4 and R.sup.5 individually can be alkyl or polyhaloalkyl of from 1 to 6 carbon atoms; with the proviso that when B is a naphthyl group attached through an oxygen to the number 4 carbon atom of the phenyl group, then (a) if X is halogen and is mono or disubstituted in the ortho position of a benzoyl ring (b) if Z, Z.sup.1, R.sup.2 and R.sup.3 are hydrogen and (c) if Y represents a halogen substituted at the number three carbon atom of the phenyl ring, or if such carbon atom contains only hydrogen then R and R.sup.1 can not both be hydrogen or halogen or a combination of hydrogen and halogen.

A preferred class of bicyclooxyphenyl ureas coming within the above generic formula can be represented by: ##STR2## wherein D is nitrogen or carbon and X, Z, Y, B, Z.sup.1 and n are as previously indicated, and m has a value of from zero to four with the same proviso pertaining to X, and Y and B as herebefore indicated.

The B moiety of the above formula is a bicyclic fused ring system which can be attached to the linking oxygen atom through a carbocyclic ring. Hence, particularly preferred compositions are those presented by the following formula: ##STR3## wherein the substituents are as previously indicated.

Illustrative of the B moieties which are linked to the phenyl group through oxygen are the following: ##STR4## wherein the substituents are as previously defined.

It is readily apparent that preceding formulae encompass a wide variety of novel ureas and include but are not limited to compositions such as the following:

It is necessary for these substituents to be at the ortho positions of the benzoyl moiety. It is preferred to have the Y and Y.sup.1 substituent in the three and five positions of the phenyl ring. The most effective compounds are those when Y.sup.2 =hydrogen, Y=Y.sup.1 =chloro or methyl or Y=methyl and Y.sup.1 =chloro or hydrogen; when Y.sup.2 =methyl, Y=methyl and Y.sup.1 =chloro.

The most pesticidally effective B moieties are (i) and (ii). ##STR9##

It is preferred to have a R substituent at carbon four of the 1-naphthyl or 5,6,7,8-tetrahydro-1-naphthyl moiety. The highest activity was observed when this substituent is chloro, methoxy or dimethylamino group.

The novel compositions of this invention can be conveniently prepared by two different methods. In the first method a bicyclooxyaniline is reacted with an arylisocyanate as illustrated below for the preparation of a 1-(bicyclooxyphenyl)-3-benzoyl urea: ##STR10## wherein: D, X, Y, n R, R.sup.1, m and A are as previously described.

Alternatively, the compositions may be prepared through the reaction of a bicyclooxyphenylisocyanate with an amide according to the following reaction: ##STR11## wherein: D, X, Y, n, R, R.sup.1, m and A are as described previously.

In general, the reactions illustrated in both methods proceed smoothly without the need of additional reagents. However, the use of an organic solvent is preferred. Generally any solvent which is inert towards the reactants is suitable, although aromatic hydrocarbon and halogenated hydrocarbon solvents are preferred. Such solvents as toluene and 1,2-dichloroethane are especially preferred. These reactions will, in general, occur over a wide temperature range.

The intermediates shwn in the two methods for the preparation of the compositions of this invention can be prepared according to known procedures. For example, the substituted benzoylisocyanates are prepared from the substituted benzamides following the general procedure of Speziale et al., J. Org. Chem., 27,3742 (1962).

The benzamides themselves are either available commercially or can also be prepared according to known processes.

The anilines can be prepared according to the two step sequence illustrated below: ##STR12## wherein: Y, R, R.sup.1, n and A are as previously defined.

The reaction of the bicyclic phenol with a 4-chloro nitrobenzene proceeds in the presence of a base in an inert solvent at an elevated temperature to afford the nitro-ether.

Suitable bases include sodium hydride, potassium hydroxide and potassium carbonate. Suitable solvents include toluene, dimethylformamide and dimethylsulfoxide. If the reaction is heterogeneous a phase-transfer agent such as quaternary ammonium halide or crown ethers complex may be added.

The reduction of the nitro ether to the aniline can be accomplished under a hydrogen atmosphere using a heterogeneous hydrogenation catalyst. Such catalysts include platinum or palladium on an inert support or a Raney nickel catalyst. In general these reductions can be preformed under a wide range of temperatures and pressures. However, it is preferrable to use a pressure range 80-120 psi at ambient temperature. The solvents of choice include aromatic hydrocarbons, such as toluene or alcohols such as ethanol. Alternatively, this reduction may also be accomplished by a chemical reductant such as a transistion metal or its salts in a mineral acid solution. In general tin or iron and their salts in hydrochloric acid are preferred. A co-solvent such as dioxane or alcohols may be added to improve the reactant solubility in the reaction medium. The aniline can be converted to the isocyanate by the reaction with phosgene employing generally accepted procedures.

Both the bicyclic phenols and the nitrochlorobenzenes are available commercially or may be prepared by well known methods from the chemical literature.

As hereinbefore indicated and as set forth in the examples, the compositions of this invention are useful as insecticides and acaricides in certain cases are more effective than known benzoyl ureas.

NMR (DMSO-d.sub.6): .delta.1.40 (s, 6H), 3.05 (s, 2H), 6.3-8.0 (m, 10H), 10.20 (broad s, 1H), 11.47 (broad s, 1H).

In a similar manner 4-(4-benzothienyloxy)-3-chloroaniline is prepared through the condensation of 4-hydroxybenzothiophene with 3,4-dichloro-1-nitrobenzene in the presence of anhydrous potassium carbonate in hot DMF. This product is reduced either chemically with stannous chloride in hydrochloric acid using dioxane as a co-solvent or through catalytic hydrogenation to produce the desired aniline. In a similar manner 4-(4-benzothienyloxy)-3,5-dichloroaniline is prepared from 1,2,3-trichloro-5-nitrobenzene.

Tables I through VI below set forth the physical properties of each of the benzoyl ureas prepared by the processes of this invention:

Selected bicyclooxyphenyl ureas representative of those prepared in accordance with this invention and having the same utility were tested with respect to their insecticidal and miticidal activity.

Suspensions of the test compounds were prepared by dissolving one gram of compound in 50 milliliters of acetone in which had been dissolved 0.1 gram (10 percent of the weight of compound) of an alkylphenoxy-ethanol surfactant, as an emulsifying or dispersing agent. The resulting solution was mixed into 160 milliliters of water to give roughly 200 milliliters of a suspension containing the compound in finely divided form. The thus prepared stock suspension contained 0.5 percent by weight of compound. The test concentrations employed in the tests described hereinbelow were obtained by diluting the stock suspension with water. The test procedures were as follows:

Larvae of the southern armyworm (SAW) (Spodopteraeridania, (Cram.)), reared on Tendergreen bean plants at a temperature of 80.+-.5.degree. F. and a relative humidity of 50.+-.5 percent, constituted the test insects.

The test compounds were formulated by diluting the stock suspension with water to give a suspension containing 500 parts of test compound per million parts of final formulation. Potted Tendergreen bean plants of standard height and age were placed on a revolving turntable and sprayed with 100-110 milliliters of test compound formulation by use of a DeVilbiss spray gun set at 10 psig air pressure. This application, which lasted 25 seconds, was sufficient to wet plants to run-off. As a control, 100-110 milliliters of a water-acetone-emulsifier solution containing no test compound were also sprayed on infested plants. When dry, the paired leaves were separated and each one was placed in a 9 centimeter Petri dish lined with moistened filter paper. Five randomly selected larvae were introduced into each dish and the dishes were closed. The closed dishes were labeled and held at 80.degree.-85.degree. F. for five days. Although the larvae could easily consume the whole leaf within twenty-four hours, no more food was added. Larvae which were unable to move the length of the body, even upon stimulation by prodding, were considered dead.

Fourth instar larvae of the Mexican bean beetle (MBB), (Epilachna varivestis, Muls.), reared on Tendergreen bean plants at a temperature of 80.+-.5.degree. F. and 50.+-.5 percent relative humidity, were the test insects.

The test compounds were formulated by diluting the stock suspension with water to give a suspension containing 500 parts of test compound per million parts of final formulation. Potted Tendergreen bean plants of standard height and age were placed on a revolving turntable and sprayed with 100-110 milliliters of test compound formulation by use of a DeVilbiss spray gun set at 10 psig air pressure. This application, which lasted 25 seconds, was sufficient to wet plants to run-off. As a control, 100-110 milliliters of a water-acetone-emulsifier solution containing no test compound were also sprayed on infested plants. When dry, the paired leaves were separated and each was placed in a 9 centimeter Petri dish lined with moistened filter paper. Five randomly selected larvae were introduced into each dish, and the dishes were closed. The closed dishes were labeled and held at a temperature of 80.+-.5. for five days. Although the larvae could easily consume the leaf within 24 to 48 hours, no more food was added. Larvae which were unable to move the length of the body, even upon stimulation, were considered dead.

Adults and nymphal stages of the two-spotted mite (Tetranychus urticae Koch) reared on Tendergreen beans under controlled conditions (80.+-.5.degree. F. and 50.+-.5 percent relative humidity). Infested leaves from the stock culture are placed on the primary leaves of 2 bean plants 6-8 inches in height. A sufficient number of mites for testing (150-200) will transfer from the excised leaves to the fresh plants.

Infested Tendergreen bean plants of standard height and age are placed on a revolving turntable. A formulated water mixture of the chemical (100 mL) is applied to the plants by use of a DeVilbiss spray gun with air pressure set at 40 pounds. Application of this volume of formulated compound takes 25 seconds. This volume of spray is sufficient to wet the plants to run-off.

The test compounds are formulated by a standard procedure of solution in acetone, addition of an emulsifier, and dilution with water. Primary spray applications are conducted at 500 ppm.

The treated plants are held at 80.+-.5.degree. F. and 50.+-.5 percent relative humidity for a period of 7 days when mortality counts of motile forms (adults and nymphs) are made.

Microscopic examination of motile forms is made on one leaf from each of the 2 test plants. Any individual which is capable of locomotion upon stimulation is considered living.

The egg of the two-spotted mite (Tetranychus urticae (Koch) obtained from adults reared on Tendergreen beans under controlled conditions (80.+-.5.degree. F. and 50.+-.5 percent relative humidity). Heavily infested leaves from the stock culture are placed on uninfested bean plants. Females are allowed to oviposit for a period of 24 hours, and the leaves of the plants are then dipped in an 1000 ppm solution of TEPP in order to kill the motile forms and prevent additional egg laying. TEPP does not affect the viability of the eggs.

The plants are placed on a revolving turntable. A formulated water mixture of the chemical (100 mL) is applied to the plants by use of a DeVilbiss spray gun with air pressure set at 40 pounds. Application of this volume of formulated compound takes 25 seconds. This volume of spray is sufficient to wet the plants to runoff. An equivalent amount of a water solution containing acetone and emulsifier in the same concentrations as the insecticidal mixture but without the candidate insecticide is also sprayed on the infested plants as a check or control.

The test compounds are formulated by a standard procedure of solution in acetone, addition of an emulsifier, and dilution with water. Primary screening tests are conducted at 500 ppm.

The treated plants are held at 80.+-.5.degree. F. and 50.+-.5 percent relative humidity for 7 days after which counts are made.

Microscopic examination is made of the plant leaves, and the number of unhatched eggs (considered dead) and empty egg shells (living eggs) are noted. The results obtained are set forth in tables VII-XI below:

In order to demonstrate the insecticidal properties of benzoyl ureas of this invention, a comparison of activity was made with a known benzoyl urea insecticide produced by Phillips Duphar of the Netherlands. The following examples set forth in Table XII demonstrate the superiority of the compositions of this invention over the known insecticide.

Although the invention has been illustrated by the preceding examples, it is not to be construed as being limited to the materials employed therein, but rather, the invention encompasses the generic area as hereinbefore disclosed. Various modifications and embodiments can be made without departing from the spirit and scope thereof.
