摘要：
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)(2)P(O)H in benzene. High selectivity were also obtained for the catalytic addition of Ph2PH to (BuC)-Bu-t=CH and to PhC=CPh.
