  Trapping Intermediates in Phosphavinyl Coupling Reactions:  Synthesis and Structural Characterization of a Novel Bis(phosphinoalkylidene)−Tantalum Complex, [{Cp*TaCl₂[C(Bu^t)−P(Cy)−]}₂]

  摘要：

  The reactions of the stable phosphavinyl Grignard reagent (Z)-[MgCl(OEt2){C(Bu-t)=PCy}] with [Cp*TaCl4] or [Cp*NbCl4] have been investigated. In both cases phosphavinyl coupling reactions are the ultimate outcome to give the known 2,4-diphosphabicyclo[1.1.0]butane, Cy2P2C2Bu2t, in the former and a mixture of this compound and its 1,2-dihydro-1,2-diphosphete valence isomer in the latter. A novel bis(phosphinoalkylidene)-tantalum complex, [{Cp*TaCl(2)f=C(Bu-t)-P(Cy)]}(2)], has been isolated and structurally characterized as an intermediate in the tantalum reaction.
