Chlorine → 2-Chloro-4-(trifluoromethoxy)phenol

참여 물질

반응 단계

Gaseous chlorine was slowly introduced to a stirred solution of 35.6 g of 4-trifluoromethoxyphenol in 100 ml carbon tetrachloride. The reaction temperature was kept at 20° to 30° C. by outer cooling. After saturaring with chlorine, the reaction mixture was stirred at 20° to 30° C. for 1 hour, cooled, washed with water, dried over anhydrous sodium sulfate, and evaporated to give a pale yellow residue. The residue was distilled under reduced pressure to give 29.8 g of 2-chloro-4-trifluoromethoxyphenol which boiled at 67°-70° C./18 mmHg.
