Exchange reactions of tetrathiophosphates with thiophosphoryl chloride were studied. The exchange of thiol groups between compounds with tetracoordinated phosphorus centers proceeds at 150-220 °C and results in the formation of dialkyl trithiochlorophosphates and alkyl(aryl) dithiodichlorophosphates or their mixtures depending on the ratio of the reagents.

Disclosed herein is a process for preparing a phosphorodichloridodithioate comprising reacting a mercaptan, phosphorus trichloride, thiophosphoryl chloride and sulfur in the presence of a base catalyst.
Process for preparing mono- and disubstituted mercapto-phosphorothionochloridates

, (2008/06/13)
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.
