An efficient cross-coupling of alkynes with alkynyl and alkenyl halides catalysed by a Ni-Cu system without any ligand has been achieved. The reaction is suggested to proceed by Ni(0) catalysis assisted by Cu(i). A series of functionalised diaryl, aryl-alkyl, aryl-heteroaryl, diheteroaryl 1,3-di-ynes and en-ynes are obtained in high yields.

Homocoupling of terminal alkynes has been efficiently achieved using catalytic amounts of CuCl2 and DBU. This methodology could be extended to couple two different terminal alkynes together by taking one of the alkyne partners, preferably the electron rich alkyne, in five fold excess than the other.
