Propargylamines are formed in high yield by three-component coupling reaction of aldehydes, terminal aryl acetylenes, and amines in DMSO in the presence of catalytic tetraalkylammonium hydroxide. This reaction does not require a transition-metal catalyst.

Described herein is a three-component coupling reaction of alkynylsilanes, aldehydes and amines by a cooperative catalytic system comprised of CuCl and Cu(OTf)(2), leading to the production of a variety of propargyl amine derivatives. This catalytic system was successfully applied to the practical preparation of 1,6-diyne derivatives via twice-performed, domino-type coupling reactions.
