Reaction Steps
2.0 g of cis-chrysanthemic acid and 43 mg of benzoyl peroxide were dissolved in 20 ml of toluene and thereto was added dropwise a solution of bromine (28 mg) in carbon tetrachloride with stirring at 80° C. over a period of 20 minutes, and the reaction mixture was stirred at the same temperature for 20 minutes. Then, a post-treatment similar to Example 1 was effected to obtain 1.87 g of chrysanthemic acid. Gas chromatographic assay thereof showed the composition: cis, 5.9%; and trans, 94.1%.
