Reaction Steps
A 100 ml flask is charged with tributylamine (15 g) and diglyme (20 ml) in a dry box. 1,1,-Dihydroperfluoropropanol (24.0 g) is added. CH2═C(CF3)CF2OSO2F (19.5 g) is added dropwise at 0-5° C. The resulting mixture is stirred at room temperature for 3 hours. The mixture is then distilled to give a liquid, which is redistilled (spinning band column) giving 27.3 g CH2═C(CF3)CF2OCH2CF2CF3, b.pt. 54° C. at 200 mm Hg. Yield is 58%. Less pure fractions are not included in the yield calculation.
