Copper‐Catalyzed Selective Semihydrogenation of Terminal Alkynes with Hypophosphorous Acid. Issue 4 (20th February 2014) - Cao, Huanyang
Abstract A novel copper‐catalyzed selective semihydrogenation of terminal alkynes using hypophosphorous acid as hydrogen donor took place efficiently to afford the corresponding alkenes in high yields. A broad range of substituted terminal aromatic and aliphatic alkenes, including terminal dienes and enynes bearing internal triple bonds, can be efficiently synthesized by this reaction.
