摘要: 应用乙基二硫化磷可制取O-烷基乙基二硫代膦酸酯[1];从而可以进行此类杀虫剂的合成[2].G.Schrader先后合成S,S-(3,4二氯苯基)三硫代乙基膦酸酯及S-乙基S-乙硫乙基三硫代甲基膦酸酯,生物试验证明它们是很好的杀虫剂,且对温血动物毒性低[3].我们对乙基三硫代膦酸酯的制备进行了一些试验,最后以乙基三硫代膦酸铵和N-取代α-氯代乙酰胺反应,制取S-烷基S-(N-取代氨基羰甲基)乙基三硫代膦酸酯.

Abstract: In the presence of benzene as solvent, the ammonium S-alkyl ethyl-phosphonotrithioates were prepared by reaction of the ethylthionophosphine sulfide with mercaptans for 6-8 hrs, and then into which the dried ammonia gas was introduced.Through the reaction between those above ammonium salts and N-substituted a-chloroacetylamide, we obtained twelve S-alkyl-S-(N-substituted carbamoyl-methyl) ethylphosphono-trithionates. But, we could not obtain the products by means of the sodium salts instead of the ammonium salts.
