新型含磷拟除虫菊酯的合成及生物活性

Synthesis and Biological Activity of Pyrethroids Containing Phosphonyl Moiety

以α 羟基芳基膦酸酯为中间体分别与 2 (4 氯苯基 ) 3 甲基丁酰氯 ,二氯菊酰氯作用 ,合成了两类 8种新型的含磷拟除虫菊酯化合物。结构均经过确证 ,并进行了杀虫、杀螨的活性测试。结果表明 ,在 5×10 -5mol/L浓度下 ,化合物 4b、4d和

Four 2-(4-chlorophenyl)-3-methyl-butyl phosphorates and four 3-(2,2-dichloroviny)-2,2-dimethyl-cyclopropane carboxyl phosphorates were synthesized from the intermediate α-hydroxylaryl phosphorates with 2-(4-chlorophenyl)-3-methyl-butyl chloride and 3-(2,2-dichlorovinyl)-2,2-dimethyl-cyclopropane carbonyl chloride, respectively . All compounds synthesized were identified by ~1H NMR, IR and MS. Preliminary bioassay showed that compounds 4b, 4d and 5a, have consierable acaridcidal activities.
