  • Preparation of S-chloromethylated O-alkyl substituted phosphodithioic acids
    Patent number: 4264533
    Abstract: A novel and efficient method for preparing S-chloromethyl derivatives of O-alkylphosphorodithioic acids involves reacting the S-hydroxymethyl derivative of such an acid under substantially anhydrous conditions with a suitable acid chloride in a chemically unreactive organic liquid which is a solvent for both said S-hydroxymethyl derivative and said acid chloride. Suitable acid chlorides are PCl.sub.5, PCl.sub.3, acetyl chloride, chlorinated derivatives of acetyl chloride, oxyalyl chloride, phosgene, thionyl chloride, sulfuryl chloride, aryl sulfonyl chlorides and chloro- or nitro-substituted aryl sulfonyl chlorides.
