Abstract

A simple, yet efficient system for PdCl2/CuI to catalyze the homo-coupling reactions of various terminal alkynes has been developed using 3-(diphenylphosphino)propanoic acid as ligand in the presence of oxygen. The alkynes, including aromatic, heteroaromatic and aliphatic alkynes, were transformed at room temperature into the corresponding 1,3-diynes in moderate to excellent yields. The turnover number was up to 1.04 × 103. Copyright © 2015 John Wiley & Sons, Ltd.
