具有生物活性有机磷化合物研究 ⅩⅩⅡ.S-烯丙基、S-丙二烯基硫赶磷酸酯的合成与杀虫活性

STUDIES ON BIOLOGICAL ACTIVE ORGANOPHOSPHORUS COMPOUNDS ⅩⅩⅡ.Synthesis and Insecticide Activity of S allyl and S propadienylphosphorothiolates

利用［３，３］重排反应分别将烯丙氧基不对称硫逐磷酸酯和炔丙氧基不对称硫逐磷酸酯转化成Ｓ－烯丙基硫赶磷酸酯和Ｓ－丙二烯基硫赶磷酸酯，用元素分析、ＩＲ、ＮＭＲ和ＭＳ对合成的硫赶磷酸酯进行表征，并进行了杀虫活性试验，初步研究了它们的构效关系．

The thermal sigmatropic type rearrangement of O aryl O methyl O propargyl thionophosphates in the solvent such as p xylene,toluene or benzene and O aryl O methyl O allyl thionophosphates on SiO 2 to provide new compounds was described.The structures of these new compounds were identified by IR, 1H NMR,MS and elementary anaylsis. The preliminary biological tests showed that a part of new compounds had better insecticide activity than their precursor.
