Mono- and disubstituted mercaptophosphorothionochloridates are prepared by reacting a disubstituted sulfide having the formula wherein each R is an independently selected alkyl, cycloalkyl or benzyl, with phosphorus pentasulfide and thiophosphorus trichloride at a temperature from about 150° to about 300° C. A molar ratio of R2 S to P4 S10 to P(S)Cl3 of 6:1:8 is preferred where the monosubstituted compound is desired, while a ratio of 6:1:2 is preferred where the disubstituted compound is desired. The compounds are useful as intermediates for compounds which exhibit biocidal properties, particularly insecticides and herbicides.
