The preparation of α-cyanoenamines 4 via the condensation of casrbonyl compounds 2 with α-(N-methylanilino)-acetonitrile (1) carried out in the presence of a mixture of powdered potassium hydroxide and potassium carbonate and tetra-n-butylammonium bromide as a catalyst (solid-liquid catalytic two-phase system) is described. This reaction comprises a useful one-carbon chain lengthening of carbonyl compounds.

The reactions of α-anilino alkenenitriles with iodobenzene catalyzed by palladium gave amides and benzonitrile. A general mechanism is proposed to explain the chemoselective arylation at the cyano group.
