Exchange reactions of tetrathiophosphates with thiophosphoryl chloride

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.

Process for preparing phosphorodichloridodithioates by reacting alkyl mercaptans with PCI3 PSCI3 and sulfur

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

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.
