Abstract:
Alkyl or aryl phosphonothioic dihalides and phosphinothioic monohalides are prepared by reacting an alkyl halide or an aryl halide with a pentavalent thiophosphorus compound having at least two halogens attached thereto, and preferably three halogens such as thiophosphoryl halide, in the presence of a halogen acceptor such as phosphorus, or sulfur under at least autogenous pressure at a temperature of from 200 DEG C. to 450 DEG C.
