Combating pests with 3-(2,3-dichloro-3,3-difluoro-prop-1-en-1-yl)-2,2-dimethyl-cyclo-propanecarboxylic acid fluoro-benzyl esters

摘要

3-(2,3-Dichloro-3,3-difluoro-prop-1-en-1-yl)-2,2-dimethyl-cyclo-propan ecarboxylic acid fluoro-benzyl esters of the formula <IMAGE> in which R1 represents hydrogen, cyano, alkyl with up to 4 carbon atoms, alkenyl with up to 4 carbon atoms or alkynyl with up to 4 carbon atoms, and R2 represents a phenyl radical which is substituted by fluorine and/or optionally fluorine-substituted phenoxy, with the proviso that the radical R2 in total contains at least one fluorine substituent, which possess pesticidal activity.
