摘要: 通过1-甲硫基亚乙基氨-甲基氨基甲酸酯与二氯亚砜反应,制得一系列新的含硅氨基甲酸酯衍生物。化合物结构经1HNMR、元素分析IR和MS确证,测定了化合物3a的晶体结构。生物测定结果表明,该类化合物对蚊子、粘虫、玉米螟等多种害虫具有优良的杀虫活性,且与母体灭多威相比,在哺乳动物安全性方面有显着提高。

Abstract: A series of new silicon-containing carbamate derivatives 3 have been prepared from reaction of 1-methylthio-ethylideneamino-methyl carbamate (Methomyl) 1 with thionyl chloride. Their structures were confirmed by 1H NMR,elemental analysis,IR and MS. The crystal structure of compound 3a was determined by X-ray diffraction method.The bioassay results showed that compound 3 have a high insecticidal activity against mosquito,armyworm, European corn borer, flour beetle and cowpea aphid and a substantial improvement in acute mammalian safety toward male and female mice when compared to that of parent Methomyl.

Key words: carbamates, silicon derivative, biological activity
