Propionitrile → 2-(Pentafluoropropionyl)propionitrile

Participants

Reaction Steps

Propionitrile (13.2 g, 0.24 mole), ethyl pentafluoropropionate (23.05 g, 0.12 mole) and a solution of n-butyllithium in n-hexane (168 ml, 0.264 mole) were reacted according to the same procedure as described in Example 1 to give 22.72 g (crude yield 94.1%) of the crude title compound. The yield calculated as the pure product was 84.1%. When the resulting compound was dissolved in CDCl3 and its NMR was measured, the ratio of the keto form/the enol form was found to be 71/29, b.p. 63°-65° C./28 mmHg.
