探讨了O-烯丙基硫逐磷酸酯热重排制备S-烯丙基硫赶磷酸酯的反应条件,结果表明:反应在SiO2上进行几乎可定量地完成.运用这一合成方法,制备了14个不对称结构的新型硫赶磷酸酯,所有的化合物均经IR, 1H NMR, 31P NMR及元素分析表征.生物活性试验显示5a,5e, 5h, 5i及5k有良好的杀虫活性.

The thermal [3,3]-sigmatropic type rearrangement of O-allyl thionophosphates to provide S-allyl thiolophosphates was studied. The tests showed O-allyl thionophosphates were easily convertedto their thiol isomers on SiO2 in quantitative yields. The fourteen new compounds were synthesized and identified by IR, 1H NMR, 31P NMR andelemental analysis. The preliminary tests showed that compounds 5a, 5e, 5h, 5i and 5k had excellent insecticidal activity.

Key words: thiolophosphate, synthesis, rearrangement
