Elimination process from the [(diphenylphosphino)methyl]zirconium hydride [Cp2ZrH(CH2PPh2)]n

The synthesis of [Cp2ZrH(CH2PPh2)]n, 1, and its chemical behavior toward different organic or organometallic substrates are described. The chemical reduction of the hydride 1 produced a paramagnetic Zr(III) species formulated as [CpZr(η2-CH2PPh2)2], and a redistribution reaction from the unstable [Cp2ZrH(CH2PPh2)]- is suggested. The thermolytic experiment of 1 led to the Zr(III) species Cp2ZrH and [Cp2Zn(η2-CH2PPh2)], and a mechanistic pathway implying the reductive elimination of the phosphine CH3PPh2 is proposed. Indirect evidence comes from the thermolysis of [Cp2ZrD(CH2PPh2)]n and [(C5D5)2ZrD(CH2PPh 2)]n or from the reactivity of 1 with PhC≡CPh, Cp2Zr(Ph)2, or Cp2Zr(η4-butadiene). A Zr(IV)-Zr(II) homodimetallic hydride [Cp2Zr(μ-H)(μ-CH2PPh2)ZrCp2] is postulated as an intermediate in the decomposition scheme of 1.

Formation of Zirconium(III) Complexes by Thermolysis of (η5-C5H5)2ZrH(CH2PPh2)

E.s.r. spectra obtained when the thermolytic reduction of (η5-C5H5)2ZrH(CH2PPh2) in the presence of a phosphine PR3 is monitored, compared with those obtained from (η5-C5H5)2ZrH2, led to the characterization of a monophosphine zirconium(III) hydride formulated as the adduct (η5-C5H5)2ZrH(PR3) and a new species assumed to be a metallated complex such as .
