An efficient zinc-catalyzed cross-coupling reaction of aryl iodides with terminal aromatic alkynes

摘要

The first Zn-catalyzed protocol for C(sp(2))-C(sp) cross-coupling reactions for the synthesis of disubstituted alkynes is described. A broad spectrum of functional groups is tolerated during the catalysis and successfully afforded a variety of diaryl substituted acetylenes. (C) 2015 Elsevier Ltd. All rights reserved.
