New Synthetic Strategies for Structured Silicones Using B(C6F5)3

Part of the Advances in Polymer Science book series (POLYMER, volume 235)


The dehydrocarbonative condensation of alkoxysilanes + hydrosilanes in the presence of the Lewis acid catalyst B(C6F5)3 (R3SiOR + HSiR3 ′′ → R3SiOSiR3 ′′ + R H) – described throughout this review as the Piers-Rubinsztajn reaction – provides a new, mild strategy for the controlled synthesis of silicones. In this review we examine the mechanistic parameters that control the reaction, and outline the types of accessible small molecules, linear, branched, and cross-linked materials (resins and elastomers) that can be prepared using this and related reactions.

    General Electric silicone nomenclature: M = Me3SiO1 ∕ 2, D = Me2SiO2 ∕ 2, T = MeSiO3 ∕ 2, and Q = SiO4 ∕ 2. The subscript nomenclature is used to denote, for example with SiO4 ∕ 2, that there are four single bonds to oxygen from silicon, and that each oxygen bonds to another silicon through a single bond, i.e., Si(OSi)4 rather than SiO2, which might imply Si = O double bonds.Google Scholar
