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
