摘要：

In the reaction of Cp2ZrCl2 with Mg and (2,4,6-Me3C6H2)PH2, the mono(phosphinidene)-bridged species (Cp2ZrCl)2(mu-2-P(2,4,6-Me3C6H2)) (1) was isolated and crystallographically characterized. In the related reaction of Cp2ZrCl2 With Mg in the presence of CyPH2, the Zr(III) phosphide-bridged zirconocene dimer [Cp2Zr(mu-2-PCyH)]2 (2) was isolated. The structure of 2 has been confirmed crystallographically. Preliminary mechanistic information obtained from the analogous reaction employing Cp*2ZrCl2 suggests the formation of the hydridephosphide Cp*2Zr(PHCy)H and the terminal phosphinidene intermediate Cp*2Zr = PCy.
