Abstract
O, O-Dialkyl phosphoro(-no) thioic acids derivatives are dealkylated with a queous dimethylamine to give ammonium phosphoro (-no)thioates , which are c hlorinated with phosphorus oxychloride to afford phosphoro (-no)chloridothi onates. This novel reaction provides a new convenient method for synthesis of phosphoro(-no)chloridothionates, especially those containing asymmetrica l phosphorus atom. The chlorination mechanism is also discussed.
