摘要

Copper-catalyzed oxidative coupling reactions of terminal alkynes have been performed at room temperature by using enaminone as effective ligand. Both symmetrical and unsymmetrical 1, 3-diynes bearing various functional groups have been synthesized in moderate to excellent yields via homo-and cross-coupling reactions.
