Process for preparing dialkyl and diaryl phosphonothioic halides

Dialkyl or diaryl phosphonothioic halides are prepared by contacting an alkyl or aryl halide, respectively, with phosphorus sesquisulfide, P4S3, under at least autogenous pressure at a temperature of from about 200 DEG to about 400 DEG C. The compounds obtained are useful as pesticides and as interm...

description Dialkyl or diaryl phosphonothioic halides are prepared by contacting an alkyl or aryl halide, respectively, with phosphorus sesquisulfide, P4S3, under at least autogenous pressure at a temperature of from about 200 DEG to about 400 DEG C. The compounds obtained are useful as pesticides and as intermediates in preparation of pesticides and other organo-phosphorus compounds.
