✦ Synopsis

A variety of unsymm~rical 1,4-biaryl-l,3-butadiyne dsrivatives are synthesized by a coppet(I)-c~alyzed cross-coupling reaction of alkynylsilanes with l-chloroalkynes in moderate to good yields. These reactions axe derived from the transmetalation of an aikynyl group from silicon to copper in a polar solvent.

## Abstract A copper‐catalyzed cross‐coupling reaction of alkynes with aryl iodides is described. The system tolerates a broad range of functional groups and enables the use of sterically demanding substrates with only 1.0–2.5 mol‐% of Cu~2~O and 1.0–2.5 mol‐% of xantphos as the catalyst.
