반응 단계
2.0 g of cis-chrysanthemic acid and 23 mg of azobisisobutyronitrile were dissolved in 20 ml of toluene and thereto was added dropwise a solution of bromine (21 mg) in carbon tetrachloride with stirring at 80° C. over a period of 20 minutes. Thereafter, a treatment similar to Example 1 was carried out to obtain 1.91 g of chrysanthemic acid. Gas chromatographic assay thereof showed the composition: cis, 9.8% and trans, 90.2%.
