有机磷杀虫剂E605是一种较好的接触杀虫剂,在农业上得到广泛的使用,可是它对人畜毒性较高,因此围绕着E605结构寻找高效低毒的磷制剂早已引起了广泛的注意。根据硫代磷酸酯的毒性比磷酸酯低的规律,前人仿照E605结构改变其脂基或芳基已制备出一些具有杀虫特效的二硫代磷酸酯,但三硫代磷酸酯到日前还很少报导,至于该类化合物的性质和药效更是研究不多。为寻求高效低毒的农药,我们认为在此方面有进一步探索的必要。在我们工作前期,G.Schrader从S、S-二乙基亚磷酰氯[(C_2H_5S)_2PC1]和取代
Organophosphorus insecticide E605 is a good contact insecticide, widely used in agriculture, but it has high toxicity to humans and animals. Therefore, the search for efficient and low toxicity phosphorus preparations around the E605 structure has caused widespread note. According to the toxicity of phosphorothioate phosphoric acid ester lower than the law, the previous model in the light of the E605 change its lipid or aryl has been prepared with some insecticidal effects of phosphorothioate, but trithiophosphate to date also Rarely reported, as for the nature of the compounds and efficacy is less studied. In order to seek efficient and low toxicity pesticides, we think there is a need for further exploration in this regard. In our earlier work, G. Schrader removed from S, S-diethylphosphoramidite [(C_2H_5S) _2PC1] and substituted
