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 t BuC≡CH and to PhC≡CPh.
