摘　　要：New reactions of Lawesson reagent (LR) with alpha -hydroxy (amino)nitriles have been studied. The experimental results showed that the five-membered phosphoroheterocycles 2 and 4 bearing N-P-N or S-P-N moiety could be readily prepared in high yields. Meanwhile, the possible mechanism of the reactions was also discussed.New reactions of Lawesson reagent (LR) with alpha -hydroxy (amino)nitriles have been studied.
