The reaction of nitriles and alkynyldimethylaluminum reagents, derived from trimethylaluminum and alkynes, provides a simple and efficient access to a wide range of α,β-alkynyl ketones with aliphatic, aromatic, and heteroaromatic substituents in good yield. In the cases of aryl-substituted nitriles, α,β-alkynyl N-H ketimines can also be obtained in high yield.
