In this article, it is reported that the isornerization/ chlorination reactions of nitrogen heterocyclic 0, O-dialkyl thiophosphoramidates 5 with equivalent amounts of phosphorus oxychloride give nitrogen heterocyclic S-alkyl thiophosphorochloridates 6 and 0alkyl phosphorodichloridates 3. After remo
A new method for the synthesis of S-alkyl methylthiophosphonic acid derivatives is reported. The chlorination of 0,O-dialkyl methylthiophosphonates 8 with phosphorus oxychloride proceeds with isomerization of the P = S to the P-S bond to give S-alkyl methylthiophosphonochloridates 9, which react fur
