The invention belongs to the technical field of
chemical synthesis, and relates to a
pyrethroid compound capable of being used for killing insects, in particular to a
pyrethroid compound containing a benzyl
fluorine structure, a preparation method of the
pyrethroid compound and application of the pyrethroid compound to prevention and control of pests such as resistant mosquitoes and flies. The compound is a compound as shown in a general formula I, and isomers and salts thereof. The pyrethroid compound containing the benzyl
fluorine group is novel in structure, and the activity of the pyrethroid compound containing the benzyl
fluorine group to mosquitoes and flies is obviously improved compared with the activity of an analogue containing a perfluthrin intermediate 2, 3, 5, 6-tetrafluoro-4-methylbenzyl
alcohol structure; the activity of part of compounds on resistant mosquitoes in Guangzhou areas is 2-3 times that of tetramefluthrin; the compound has a novel structure and an excellent
control effect on target sanitary pests and resistant mosquitoes, so that the compound is suitable for development of novel mosquito-repellent incense products. I
