반응 단계
To a solution of cis chrysanthemic acid (1.0 g) in toluene (9 g) was added phosphorus tribromide (0.11 g) at room temperature under a nitrogen atmosphere. Irradiation with a xenon lamp (500 W, Pyrex glass filter) 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 (0.90 g). The isomer ratio of the product was: cis, 10.0%; and trans, 90.0%.
