title: Double hydrophosphination of alkynes promoted by rhodium: the key role of an N-heterocyclic carbene ligand.
abstract: The regioselective double hydrophosphination of alkynes mediated by rhodium catalysts is presented. The distinctive stereoelectronic properties of the NHC ligand prevent the catalyst deactivation by diphosphine coordination thereby allowing for the closing of a productive catalytic cycle.
