, p. 1465 - 1474 (2002)
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

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.
New approach to vinylphosphines based on Pd- and Ni-catalyzed diphenylphosphine addition to alkynes

The catalytic addition of Ph2PH to phenylacetylene regioselectively leads to the Ph2P-CH=CHPh isomer with Pd(PPh3)4 in acetonitrile and to the Ph2P-C(Ph)=CH2 isomer with Ni(acac)2/(EtO)2P(O)H in benzene. High selectivity were also obtained for the catalytic addition of Ph2PH to tBuC≡CH and to PhC≡CPh.
Preparation of vinylphosphines by means of free radical addition of diphenylphosphine to alkynes and allenes
Mitchell, Terence N.,Heesche, Kerstin
, p. 163 - 170 (2007/10/02)
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.
