Facile and selective synthesis of propargylic amines and 1,6-diynes: one-pot three-component coupling reactions of alkynylsilanes, aldehydes and amines by a cooperative catalytic system comprised of CuCl and Cu(OTf)2.

[摘要]：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 prodn. of a variety of propargyl amine derivs. This catalytic system was successfully applied to the practical prepn. of 1,6-diyne derivs. via twice-performed, domino-type coupling reactions.
