A new convenient synthesis of S-alkyl O-aryl thiophosphoric acid derivatives is reported. The chlorination of O-aryl O,O-dialkyl thiophosphates with phosphorus oxychloride proceeds with isomerization to give S-alkyl Oaryl thiophosphorochloridates, which react further with various nucleophiles in the presence of base to give the title compounds.
