Here we show that palladium on carbon (Pd/C), i.e., a widely available supported Pd catalyst, is converted from an unselective to a chemoselective catalyst during the semihydrogenation reaction of alkynes, after the addition of catalytic amounts of commercially available electron-poor phosphines. The catalytic activity is <= 7 times greater, and the selectivity is comparable to that of the industrial benchmark Lindlar catalyst.Reconocimiento (by)Electron-poor phosphinesSemihydrogenation reactionAlkynesCarbon catalystsElectron-Poor Phosphines Enable the Selective Semihydrogenation Reaction of Alkynes with Pd on Carbon CatalystsArtÃculo10.1021/acs.jpclett.2c03428Abierto36689618PMC9900635
