摘要：

Catalytic double hydrophosphination of internal alkynes and primary phosphines is possible using a zirconium complex, [kappa(5)-N,N,N,N,C-(Me3SiNCH2CH2)(2)NCH2CH2N-SiMe2CH]Zr (1). The reaction proceeds via stepwise hydrophosphination to give vinyl phosphine products, which can be isolated or further converted to the respective 1,2-bis(phosphino)ethane (i.e., double hydrophosphination). The catalysis is highly selective for formation of secondary phosphine products.
