反应详情

50 g of 4-chloro-3-methylmercaptophenol, 62 g of 3,4-dichlorobenzotrifluoride and 12 g of sodium hydroxide are stirred in 150 ml of dimethyl sulphoxide for 6 hours at 142° C. The reaction mixture is then poured onto ice and extracted with toluene. Distillation of the organic phase yields 81 g of 3-(2'-chloro-4-trifluoromethylphenoxy)-6-chlorothioanisole with a boiling point of 158° C./0.4 mbar.
