The silver-promoted intermolecular aminocyanation of alkynes for the synthesis of (Z)-β-aminoacrylonitriles is reported, using N-isocyanoiminotriphenylphosphorane (NIITP) as both the nitrile and amine source. The transformation proceeds in moderate to good yields, and in a regio- and stereoselective manner, using a wide range of acetylenes.
