Alkali metal or ammonium salts of dithiophosphoric acids are known to react with alkyl halides and acyl halides,'splitting out alkali halide or ammonium halide. In the present work, this type of reaction has been extended to cover the preparation of three new series of thiophosphate esters by reaction of an alkali metal salt of an 0, O-dialkyl dithio (or monothio- ) phosphoric acid with a haloacetonitrile (A), a haloacetamide (B), or a haloacetylurea (C), ...
