Double hydrophosphination of alkynes promoted by rhodium: The key role of an N-heterocyclic carbene ligand

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.

Synthesis of vinylphosphines by hydrophosphination of alkynes in the presence of transition metal complexes

Intermolecular hydrophosphination of terminal and internal alkynes with diphenylphosphine, catalyzed by palladium and nickel complexes, was accomplished for the first time. The reaction follows the syn-addition pattern. Conditions were found which ensure

Preparation of vinylphosphines by means of free radical addition of diphenylphosphine to alkynes and allenes

Diphenylphosphine adds readily to alkynes and allenes under free radical conditions.Alkynes normally give E-vinylphosphines as the primary (kinetic) product, but Z-vinylphosphines are the main products isolated.Allenes generally give complex product mixtures in which the predominant components are vinyl phosphines formed via addition of the Ph2P. radical to the central carbon atom of the allene fragment.
