实验步骤: The title compound was prepared from 4-bromo-3-fluorophenol and 2,2,3,3,3,-pentafluoropropyl triflate with potassium carbonate in acetone at ambient temperature for 18 hours. Kugelrohr distillation provided a colorless oil, b.p. 105-110° C./12 mbar. Kugelrohr distillation provided a colorless oil, b.p. 105-110° C./12 mbar

实验步骤: A mixture of trifluoromethanesulfonic anhydride (40 mL, 0.24 mol) and 2,2,3,3,3-pentafluoropropanol (25 mL, 0.24 mol) was heated under argon at 90° C. overnight. Then, the crude mixture was distilled at atmospheric pressure to give the desired product as a colourless oil (97% yield). Then, the crude mixture was distilled at atmospheric pressure
