Exchange reactions of tetrathiophosphates with thiophosphoryl chloride
were studied. The exchange of thiol groups between compounds with tet
racoordinated phosphorus centers proceeds at 150-220 degrees C and res
ults in the formation of dialkyl trithiochlorophosphates and alkyl(ary
l) dithiodichlorophosphates or their mixtures depending on the ratio o
f the reagents.
