Novel Hyperbranched Ferrocene-Containing Poly(boro)carbosilanes Synthesized via a Convenient ”A2 + B3” Approach

摘要：

　　We report the synthesis of versatile hyperbra nched ferrocene-containing poly(boro)carbosilanes (hb PBCS) via a convenient ”A2 + B3” approach.Two types of hb-PBCS are obtained by the hydrosilylation of 1,1′-bis(dimethylsilyl)ferrocene (A2) with trivinylmethylsilane (B3)followed by modification with 9-borabicyclo”3.3.1”nonane (9-BBN) and by the hydroboration of 1,1′-bis(dimethyl vinylsilyl)ferrocene (A2) with the borane-dimethyl sulfide complex (B3), respectively.Size exclusion chromatography (SEC) results demonstrate that the well-soluble hb-PBCS possess appreciable weight-average molecular weight (Mw SEC) up to 62 300 g/mol with the polydispersity index (PDI) of 1.95-4.51.
