摘要:
A method for producing a (Z)-cyanoalkenyl-cyclopropanecarboxylic acid compound, which includes the step of isomerizing an (E)-cyanoalkenyl-cyclopropanecarboxylic acid compound (1) into a (Z)-cyanoalkenyl-cyclopropanecarboxylic acid compound (2) in the presence of at least one isomerizing catalyst selected from the group consisting of bromine, hydrogen bromide, brominated carboxylic acids, brominated phosphorus compounds, N-brominated imide compounds, N-brominated amide compounds, brominated alkylsilane compounds, thionyl bromide, brominated boron compounds, brominated aluminum compounds, thiol compounds, disulfide compounds, thiocarboxylic acid compounds, nitric acid and nitrate salts: wherein R 1 and R 2 represent, R 1 represents an alkyl group which may have a substituent, or a halogen atom, and R 2 represents a hydrogen atom, an alkyl group which may have a substituent, or a benzyl group which may have a substituent.
