A series of new pyrethroids containing γ-aryl allyl alcohol moieties were synthesized by using the esterification of 2,2-dimethyl-3-(2,2-dimethy vinyl)cyclopropane carbonyl chloride and 3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropane carbonyl chloride with γ-aryl allyl alcohols. Their structures were confirmed by means of IR,1H NMR,MS and elementary analysis.The preliminary biological test shows that some of the compounds have highly insecticidal activities,but the knock down activities against mosquito are lower than PY116.
