Allenes. Part XXVI. The synthesis of enaminic nitriles by the nucleophilic addition of amines to allenic nitriles

Abstract

Unconjugated or conjugated enaminic nitriles may be obtained quantitatively by Michael addition of amines to 1-cyanoallenes, according to the reaction conditions. Both series of enamines are hydrolysed to β-keto-nitriles. I.r., u.v., and n.m.r. spectra are discussed.
