研究了茂锆和铪茂甲硅烷基衍生物CpCp'M(SiR 3 )Cl (Cp=η 5 -C 5 Me 5 ; M=Zr 或Hf; R=Me 或SiMe 3 ) 与氢硅烷的反应。观察到的产物取决于起始材料的性质，因为在某些情况下，初始的σ-键复分解产物通过脱氢偶联过程进一步反应。例如，Cp Z r(SiMe 3 )Cl与PhSiH 3 反应生成直接产物Me 3 SiH 2 Ph)Cl，然后与PhSiH 3 快速结合生成[Cp 2 ZrHCl] n 、PhH 2 Si-SiH 2 Ph和PhH 2 Si-SiH 2 Ph
Reactions of zirconocene and hafnocene silyl derivatives CpCp'M(SiR 3 )Cl (Cp=η 5 -C 5 Me 5 ; M=Zr or Hf; R=Me or SiMe 3 ) with hydrosilanes have been investigated. The observed products depend on the nature of the starting materials, since in some cases the initial σ-bond metathesis products react further via dehydrocoupling processes. For example, Cp Z r(SiMe 3 )Cl reacts with PhSiH 3 to gtive the direct products Me 3 SiH 2 Ph)Cl, which then combines rapidly with PhSiH 3 to produce [Cp 2 ZrHCl] n ,PhH 2 Si-SiH 2 Ph, and PhH 2 Si-SiH 2 Ph
