More Information
Summary:Novel dithiolphosphoric acid triesters of the formula <FORM:1083377/C2/1> where R is alkyl, alkenyl, alkinyl or haloalkyl, R1 is halogen, nitro, C1- 4 alkyl or alkoxy, and n is O, 1 or 2, are prepared by reacting a phosphoric acid monoester dihalide of the formula ROP(O)(Hal)2, where Hal is a halogen atom, with the appropriate thiophenol in the form of its salts, preferably alkali metal or ammonia salts, or in the presence of acidbinding agents. The reaction is preferably carried out in the presence of solvents or diluents and at normal pressure, but increased or reduced pressure may be employed. The dihalide compound is preferably added dropwise to the thiophenol and cooling may be necessary. The compounds have fungitoxic properties.ALSO:Fungicidal compositions contain at least one compound of the formula: <FORM:1083377/A5-A6/1> where R is alkyl, alkenyl, alkinyl or haloalkyl, R1 is halogen, nitro, C1-4 alkyl or alkoxy, and n is o, 1, or 2, together with a carrier or diluent. Suitable carriers or diluents are aromatic hydrocarbons, which may be chlorinated, paraffins, alcohols, amines, water, natural and synthetic stone powders. Emulsifying and dispersing agents and other plant protecting agents such as fungicide harbicides, insecticides and bactericides may also be present and the compositions may be formulated as solutions, emulsions, suspensions, powders, pastes and granulates. They may be applied by sprinkling, dispersion, spraying or atomisation.
