合成了１４个（１－甲硫基亚乙基）氨基甲基氨基甲酸酯（灭多威）１的新型含硅衍生物３。测定了其杀虫活性和抗乙酰胆碱酯酶活性。结果表明该类化合物具有很好的杀虫活性，在５０μｇ／ｍＬ浓度下，对粘虫ＭｙｔｈｉｍｎａｓｅｐａｒａｔａＷａｌｋｅｒ几乎全部具有１００％杀灭效果。以美洲大蠊Ｐｅｒｉｐｌａｎｅｔａａｍｅｒｉｃａｎａ为试材，大部分化合物的抗乙酰胆碱酯酶活性与母体灭多威１相当。 A novel silicon-containing derivative 3 of 14 (1-methylthioethylidene) aminomethylcarbamate (methomyl) 1 was synthesized. Its insecticidal activity and anti-acetylcholinesterase activity were measured. The results show that the compounds have very good insecticidal activity, at a concentration of 50μg / mL, the mythimnapara Walker Walker almost all have a 100% killing effect. Taking Periplaneta americana of the American cockroach as a test material, most of the compounds have the same anti-acetylcholinesterase activity as the parent methomyl 1.
