Procedure

Pentafluorophenol (7.5 g, 0.040 mole) and triethylamine (4.5 g, 0.044 mole) in dry ethyl ether (7 ml) are added gradually to CH2═C(CF3)CF2OSO2F (11 g, 0.045 mole) in ethyl ether (14 ml) at 20° C. The reaction mixture is agitated at 20° C. for 30 minutes and washed in turn with water, dilute aqueous HCl, water, sodium bicarbonate solution, and water and the resulting ether solution is dried over MgSO4. Distillation of the dried mixture gives CH2═C(CF3)CF2OC6F5 (9.8 g, 73% yield, b.pt. 86-88° C. at 20 mm Hg).
