Alkyl- or arylphosphonothioic dihalides are prepared by contacting a dialkyl or diaryl thioether with various phosphorus containing reactants including: PCl3, PBr3, P(S)Cl3, P(S)Br3, P4S3, P4S5, P4S7, P4S1O and elemental phosphorus under at least autogenous pressure at a temperature of from about 200 DEG C. to about 400 DEG C. The compounds obtained are useful as constituents in insecticides, fungicides, pharmaceuticals, and as intermediates in preparation of other organophosphorus compounds.
