Although the prior art discloses phosphoroamidothioate and phosphoroamidodithioate compounds having pesticidal, including insecticidal, activity, there remains a need for pesticidal compounds having improved pesticidal efficacy, and diminished detrimental effects such as mammalian toxicity and environmental waste, especially against soil insects such as the corn rootworm.
The prior art, including the several Magee patents described above which constitute the closest art known, do not provide any specific teaching illustrative of the insecticidal activity of the compounds therein disclosed when applied in the soil to protect against soil organisms. It is well known to those skilled in the art that organophosphates having a high order of contact insecticidal efficacy when applied to aerial, or foliar, portions of plants offer relatively little economic value as plant protectants when applied, or introduced, into the soil environment of the plants. Organophosphates tend to be susceptible to rapid degradative processes in the soil due to the combination of such factors as the hydrolytic action of soil moisture, unfavorable soil pH conditions, both of the above being exacerbated by the presence of soil microflora and fauna capable of rendering the insecticidal compound inactive. Application of a pesticide to the soil in ordinary agricultural practice does not necessarily or usually coincide with the presence of susceptible life stages of the target pest. For example, the hatching of insect eggs may be either delayed or it may occur over an interval of several days to several or many weeks. Insect ova are not generally affected by organophosphate pesticides. Thus, pesticidal compounds having satisfactory residual activity, especially in the soil--pesticidal compounds that retain their pesticidal efficacy under atmosphere conditions over an interval of several days to several or many weeks--are required in order to assure satisfactory protection of plants against soil insects. Further, it is highly desirable that such pesticidal compounds having activity persistent over an interval of several days to several or many weeks elicit control over a diverse selection of soil organisms that are agricultural pests.

The compounds useful according to this invention can be obtained by several reaction sequences.

Still another method for the preparaton of hydrogencarbonyl and hydrogenthiocarbonyl phosphoroamido(di)thioates involves the reaction of diethyl chlorophosphite with a suitably substituted sulfenyl halide to obtain an intermediate O,S-disubstituted phosphorochloridothioate, corresponding to formula (III), designated below by the formula number (III'), in the reaction scheme set forth above, as follows: ##STR6##
Intermediate (III') can be further reacted as set forth in the reaction scheme illustrated above to obtain the desired end products.

The product of this reaction having the formula (VI) can be further reacted as set forth in the reaction scheme illustrated above to obtain the hydrogenthiocarbonyl phosphoroamido(di)thioate compound having the formula (VIII).
The S,S-dialkyl phosphoroamidodithioates of the invention can be prepared according to the following sequence: ##STR8##
For use as pesticides, the compounds of this invention can be used as solutions, suspensions, or mixtures, in organic solvents or formulations. For example, they can be formulated as wettable powders, emulsifiable concentrates, dusts, granular formulations or flowable emulsifiable concentrates. In such formulations, the compounds of this invention are present at a concentration of about 0.00001 to about 99%, preferably about 1 to about 95%, and are extended with an agronomically acceptable liquid or solid carrier. When desired, suitable surfactants are likewise incorporated. Surfactants commonly used in the art can be found in the John W. McCutcheon, Inc. publication "Detergents and Emulsifiers Annual."
By "agronimically acceptable carrier" is meant any substance which can be utilized to dissolve, disperse or diffuse the chemical incorporated therein without impairing the effectiveness of the toxic agent and which does not create permanent damage to such environment as soil, equipment, and agronomic crops when utilized according to recommendations.
The compounds of this invention can be taken up on or mixed with a finely particled solid carrier, as for example, clays, inorganic silicates, carbonates, and silicas. Organic carriers can also be employed.
Dust concentrates are commonly made wherein compounds are present in the range of about 20 to 80%. For ultimate applications, these concentrates are normally extended with additional solid to given an active ingredient content of from 1 to about 20%. Granular formulations are being made using a granular or pelletized form of carrier, such as granular clays, vermiculite, charcoal or corn cobs, and may contain the active ingredient from about 1 to about 25% by weight.
Wettable powder formulations are made by incorporating the compounds of this invention in an inert, finely divided solid carrier along with a surfactant which can be one or more elulsifying, wetting, dispersing, or spreading agents or a blend of these. The compounds are usually present in the range of about 10 to about 80% by weight and surfactants in from about 0.5 to about 10% by weight. Commonly used emulsifying and wetting agents include polyoxyethylated derivatives of alkylphenols, fatty alcohols, fatty acids, alkylamines, alkylarene sulfonates and dialkyl sulfosuccinates. Spreading agents include such material as glycerol mannitan laurate and a condensate of polygylcerol and oleic acid modified with phthalic anhydride. Dispersing agents include such materials as the sodium salt of the copolymer of maleic anhydride and an olefin such as diisobutylene, sodium lignin sulfonate and sodium formaldehydenaphthalene sulfonates.
One convenient method for preparing a solid formulation is to impregnate the compounds of this invention onto the solid carrier by means of a volatile solvent, such as acetone. In this manner, adjuvants, such as activators, adhesives, plant nutrients, synergists and various surfactants can also be incorporated.
Emulsifiable concentrate formulations are prepared by dissolving the compounds of this invention in an agronomically acceptable organic solvent and adding a solvent-soluble emulsifying agent. Suitable solvents are usually water-immiscible and can be found in the hydrocarbon, chlorinated hydrocarbon, ketone, ester, alcohol and amide classes of organic solvents. Mixtures of solvents are commonly employed. The surfactants useful as emulsifying agents can constitute about 0.5 to about 10% by weight of emulsifiable concentrates and can be anionic, cationic or non-ionic in character. The concentration of the active ingredients can vary from about 10 to about 80%, preferably in the range of about 25 to about 50%.
For use as pesticidal agents, these compounds should be applied in an effective amount sufficient to exert the desired pesticidal activity by techniques well known in the art. In certain situations, however, it may be desirable and advantageous to apply the compounds directly onto the loci to be protected or freed of pests without the benefit of any substantial amount of carrier. This is a particularly effective method when the physical nature of the toxicants is such as to permit what is known as "low-volume" application, that is, when the compounds are in liquid form or substantially soluble in higher boiling solvents.
The application rate will, of course, vary depending upon the purpose of such application, the compound being utilized, the frequency of dissemination, and the like.
Many of the above formulations can be utilized on animals for the control of parasites.
For use as arthropodicides, e.g. acaricides and insecticides, dilute sprays can be applied at concentrations of about 0.01 to about 20 pounds of the active ingredients per 100 gallons of spray. They are usually applied at about 0.1 to about 5 pounds per 100 gallons. In more concentrated sprays, the active ingredient is increased by a factor of 2 to 40. With dilute sprays, applications are usually made to the plants until run-off is achieved, whereas with more concentrated or low-volume sprays, the materials are applied as mists.
For use as a nematocide or as a soil insecticide, the compounds can be applied as a dilute liquid preparation or as a solid formulation, preferably a granular formulation, by broadcasting, side-dressing, introduction into the seed furrow, soil incorporation, or seed treatment. The application rate can be from about 1 to about 50 pounds per acre of active ingredient and for economic reasons, preferably from about 1 to about 25 pounds per acre.
For use as a fungicide, the organophosphorothiolate or phosphorodithioate can be applied by methods commonly employed, such as conventional high-gallonage hydraulic sprays, low-gallonage sprays, air-blast sprays, aerial sprays and dusts. The dilution and rate of application will depend upon the type of equipment employed, the method of application and diseases to be controlled, but the preferred effective amount is usually about 0.1 to about 50 pounds per acre of the active ingredient.
As a fungicidal seed protectant, the amount of toxicant coated on the seed is usually at a dosage rate of about 0.1 to about 20 ounces per hundred pounds of seed. As a soil fungicide the chemical can be incorporated in the soil or applied to the surface usually at a rate of about 0.1 to about 50 pounds per acre. As a foliar fungicide, the toxicant is usually applied to growing plants at a rate of about 0.25 to about 10 lbs. per acre.
The compounds of this invention can be utilized as the sole pesticidal agents or they can be employed in conjunction with other bactericides, fungicides, herbicides, insecticides, acaricides, and comparable pesticides.
The following examples are presented to illustrate but a few embodiments of the invention and are not to be constructed as limiting in scope. All parts and percentages are by weight unless otherwise indicated.
EXPERIMENTAL SECTION
Example 1: N-ethyl N-hydrocgencarbonyl O-ethyl S-(1-methylpropyl)phosphoroamidodithioates
A solution of N-ethyl O-ethyl S-(1-methylpropyl)phosphoroamidodithioate, 120.5 g (0.50 mol), in 750 ml of dry tetrahydrofuran (THF) is cooled to (-) 78.degree. C. while being maintained under a nitrogen atmosphere. To this there is added a hexane solution, 229 ml, containing butyllithium (0.55 mol). The resulting reaction mixture is stirred for about 0.25 hr and to this there is then added all-at-once acetic-formic anhydride (0.55 mol). The resulting reaction mixture is then warmed to 0.degree. C. over period of 2 hrs and filtered through a celite filter pad. The solvent and excess acetic-formic anhydride and acetic acid by-product are removed from the filtrate by distillation under reduced pressure to afford 118.6 g (88% of theory) of product as a clear yellow oil.
Examples 2-6 are prepared by a procedure analogous to that of Example 1 except that acetic anhydride or trifluoroacetic anhydride are substituted for acetic-formic anhydride in several of these Examples:

Example 7: N-methyl N-hydrogencarbonyl O-ethyl S-(1-methylpropyl)phosphoroamidodithoate
Formic acid, 4.48 g (0.105 mol) and acetic anhydride, 7.96 g (0.078 mol) are mixed in a flask at room temperature and allowed to stand for 0.5 hr. After cooling this mixture in an ice bath, there is added N-methyl O-ethyl S-(1-methylpropyl phosphoroamidodithioate, 12 g (0.0527 mol). The resulting reaction mixture is warmed to room temperature and stirred for 1 day at room temperature. Removal of excess acetic-formic anhydride and acetic acid by-product from the resulting reaction mixture by distillation under reduced pressure affords 13.4 g (100% of theory) of product as a colorless oil.
