实验步骤: Obtained using the procedure described in section a of Example 2, starting with 19.6 g (0.141 mole) of (2,2,2-trifluoroethoxy)acetonitrile and 0.3 g (0.013 gram-atom) of sodium in 95 ml of methanol. Reaction time: 24 hours. Yld: 15.6 g (65%), b.p.15 44°-47° C. Obtained Reaction time 24 hours 15.6 g (65%), b.p.15 44°-47° C.

反应条件: temp:25.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: At about 50° C., 26.4 g (0.40 mole) of 85% potassium hydroxide are solubilized in 100 g (1.0 mole) of 2,2,2-trifluoroethanol. After cooling at 25° C., 37.8 g (0.50 mole) of chloroacetonitrile are added dropwise to this solution. The temperature rises slowly to 40° C. and a precipitate appears. The reaction mixture is then brought gradually to 60° C.; after the addition of 300 ml of heptane, it is then brought to reflux. The whole of the vapour is condensed by means of a Dean and Stark apparatus. The lower phase of the condensate is separated after settling has taken place and distilled at atmospheric pressure. Yld: 19.6 g (28%), b.p. 125°-140° C. At about 50° C. rises slowly to 40° C. is then brought gradually to 60° C. to reflux condensed by means of a Dean and Stark apparatus The lower phase of the condensate is separated after settling distilled at atmospheric pressure
