USE: Insecticide having higher and faster insecticidal activity than the known substituted benzyl ester, and exhibiting remarkable effect even to vermins resistant to organophosphate-type or carbamate-type insecticides. Although it has high residual activity, it does not remain in the environment in contrast with the orgnic chloride insecticides, and is low toxic against man, animal and fish.
PROCESS: The compound of formulaIis prepared easily, by reacting the substituted benzyl alcohol of formula II or its reactive derivative with 2,2-dimethyl-3- (2,2-dibromovinyl)cyclopropanecarboxylic acid or its reactive derivative in the presence of a tert-amine at room temperature or under heating.
