The novel zirconocene complexes [Cp′ 2 Zr(µ-H)(SiHR)] 2 2+ [BR′ n (C 6 F 5 ) 4-n ] 2 2-(Cp′ ) Cp, MeCp, Me 5 Cp; R ) Ph or PhCH 2 ; R′ ) Bu or H) were isolated from silane dehydropolymerization reaction mixtures catalyzed by Cp′ 2 ZrCl 2 /2BuLi/B(C 6 F 5 ) 3 or by [Cp′ 2 Zr(µ-H)H] 2 /2B(C 6 F 5 ) 3 combination catalysts. A total structure analysis of these compounds, performed by multinuclear, multidimensional NMR spectroscopy, shows that each zirconocene fragment bears a positive charge, which is delocalized between the metal center and hydrosilane ligand.
