A New Convenient Synthesis of Phosphoro(-no)Chloridothionates
摘要:
A general procedure for synthesis of phosphoro(-no)chlorides, particularly unsymmetrical ones, has been developed. The method involves the dealkylation of OTO-dialkyl phosphoro(-no)thionates 1 with dimethylamine and the chlorination of O-alkyl ammonium phosphoro(-no)thioates 2 using phosphorus oxychloride as a chlorinating agent.
