A copper-silver nanoparticles-catalyzed addition of terminal alkynes to aldehydes was developed for the synthesis of propargyl alcohols. With the promotion of bipyridine ligand, the bimetallic catalyst showed highly efficient to the reaction under neat condition, and good to excellent yields were achieved for various propargylic alcohols. In this catalytic reaction, a remarkable bimetallic synergistic effect was observed, in which Ag NPs worked as the co-catalyst and improved the catalytic activity of Cu NPs significantly. The nanoparticle catalyst could be recovered and reused effectively, and no obvious reduction on catalytic activity was observed after four recycles. Furthermore, a gram-scale reaction was also carried out successfully.

Key words: Cu-Ag bimetallic nanoparticles, co-catalysis, the addition of terminal alkynes to aldehydes, propargylic alcohols, synergistic effect
