Versuchsvorschrift

After being maintained at about 25° for 2 more days, the reaction mixture, which contained sodium 3-cyanotetrafluoropropionate, was treated with 69.3 g (0.55 mole) of dimethyl sulfate, stirred, and allowed to stand overnight. Fractionation of the volatile products gave 53.3 g (58%) of methyl 3-cyanotetrafluoropropionate, bp 90°-97°.
