반응 단계
To a solution of cis chrysanthemic acid (10 g) in toluene (53 ml) was added a solution of 25% hydrogen bromide-acetic acid (1.3 g) at room temperature under a nitrogen atmosphere. Irradiation with a high pressure mercury lamp (110 W) was made for 30 minutes under stirring. After the irradiation was over, similar after-treatment as in Example 1 was applied to obtain chrysanthemic acid (9.6 g). Gas chromatography assay of the product gave the isomer ratio: cis, 8.6%; and trans, 91.4%.
