174 g of allyl alcohol was added to a mixture of 298 g of 85% flake potassium hydroxide and 750 ml of sulpholane under nitrogen, and the mixture was heated to 125°-135° C. 272 g of 4-chlorobenzotrifluoride was added over 20 minutes at this temperature. After 2 hours, the reaction mixture was cooled to 30° C., and distillation from the solvent gave 207 g of propenyl 4-trifluoromethylphenyl ether b.p.: 84°-88° C. at 15 Torr.
