摘要：

Herein, we describe an efficient copper-catalyzed cross-coupling reaction of terminal alkynes with chlorostibine 1a to synthesize a variety of Sb-alkynyl stibines. Aryl, alkyl and heteroaryl acetylenes are all tolerated. This protocol shows good functional group tolerance and broad substrate scope. These obtained Sb -alkynyl stibines were utilized as effective coupling partners to prepare 1,2,3-triazoles. The catalytic mechanism is also proposed. (C) 2022 Published by Elsevier B.V.
