An ester compound represented by formula (1): wherein R1 represents hydrogen, fluorine, C1-C4 alkyl, C1-C4 alkoxy, C1-C4 alkoxymethyl, or C1-C4 alkylthiomethyl; R3 represents hydrogen or methyl, R4 represents hydrogen or C1-C4 alkyl, and R5 represents hydrogen or C1-C4 alkyl; has an excellent pest control effect and is therefore useful as an active ingredient of a pest control agent.
tris(alkoxycarbonyl) olefins 2 or 1,1-bis(alkoxycarbonyl)-2-acyl olefins 3 in the presence of ZnBr(2) at -30 degrees C gave cis-substituted cyclopropanes exclusively. The origin of the cis stereochemistry is ascribed to the synclinal addition path of the ZnBr(2)-coordinated electrophilic olefin to 1. Application of the highly functionalized selenium- and silicon-substituted cyclopropane products to the preparation
