[Me2Si] Ansa bridged complexes of permethyltitanocene: synthesis and structural characterization of fulvene derivatives with trialkylidenemethane character†

Abstract

A series of permethylated [Me₂Si] ansa bridged titanocene complexes has been synthesized and structurally characterized by X-ray doffraction; the dialkyl complexes [Me₂Si(C₅Me₄)]TiR₂ are thermally unstable towards elimination of alkane (RH), thereby yielding fulvene derivatives [Me₂Si(C₅Me₄)(C₅Me₃CH₂)]TiR.
