摘要
本文以４－甲基－３－戊烯－２－酮为原料，经三步反应，合成了一种新型的拟除虫菊酯中间体反－３－（１－甲基－２，２－二氟乙烯基）－２，２－二甲基环丙烷羧酸，总产率为５０．０％。
Trans-3-(l-methy1-2,2-difluorovinyl)-2, 2-dimethyl cyclopropane carboxylic acid,an intermediate of a new pyrethroid,was synthesized by using 4-methyl-3-penten2-one as starting material via cyclopropylation,difluorovinylation and hydrolysis.Total yield was 50.0%.
