実験手順
A mixture of 50.48 g of methallyl alcohol, 63.2 g of 4-chlorobenzotrifluoride and 69 g of 85% flake potassium hydroxide in 175 ml sulpholane was stirred under nitrogen at 120°-145° C. for 21 hours. The mixture was then cooled, added to 200 ml water and extracted twice with 60°/80° petroleum ether. The solvent was removed and the residue was purified by fractionation to give isobutenyl 4-trifluoromethylphenyl ether, b.p.: 77°-77.5° C. at 8 Torr.
