참여 물질

반응 단계

A 100 ml flask is charged with tributylamine (15 g), diglyme (20 ml) in a dry box. 2,2,2-Trifluoroethanol (8.05 g) is added to the mixture. CH2═C(CF3)CF2OSO2F (19.5 g) is added dropwise while the mixture is cooled in an ice-water bath. 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 5.8 g CH2═C(CF3)CF2OCH2CF3, b.pt. 85-86° C., a yield of 30%. Less pure fractions are not included in the yield calculation.
