ABSTRACT:
Alkyl- or arylphosphonothioic dihalides are prepared by contacting a dialkyl or diaryl thioether with various phosphorus containing reactants including: PCl.sub.3, PBr.sub.3, P(S)Cl.sub.3, P(S)Br.sub.3, P.sub.4 S.sub.3, P.sub.4 S.sub.5, P.sub.4 S.sub.7, P.sub.4 S.sub.1 O and elemental phosphorus under at least autogenous pressure at a temperature of from about 200.degree. C. to about 400.degree. C. The compounds obtained are useful as constituents in insecticides, fungicides, pharmaceuticals, and as intermediates in preparation of other organophosphorus compounds.
