Versuchsvorschrift

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).
