The aim of this study was to explore applied and mechanistic aspects of the silane dehydropolymerization reaction catalyzed by cationic early transition metallocene compounds. This problem was dealt with by a combination of spectroscopic techniques, kinetic studies, and trapping of reaction intermediates. The results of this integrated approach allow the proposal of a new redox mechanism for the dehydropolymerization reaction which explains and predicts the reactivity and selectivity of cationic early transition metal catalysts.The novel zirconocene complexes $ rm lbrack Cp sp prime sb2 Zr( mu$-H)(SiHR) rbrack$ sb2 sp{2+}$ lbrack BR$ sp prime sb{n}$(C$ sb6$F$ sb5) sb{4-n} rbrack sb2 sp{2-}$(Cp$ sp prime$ = Cp, MeCp, Me$ sb5$Cp; R = Ph or Ph...
