N2 - The synthesis of a bis-silylated Hoveyda-Grubbs ruthenium alkylidene complex is described, as well as the preparation via the sol-gel process and the characterization of an organosilica by co-gelification with tetraethyl orthosilicate (TEOS). This material is an active supported catalyst for various metathesis reactions. The recyclability has been proven even for the formation of a trisubstituted olefin. This is the first example of an immobilized Hoveyda-Grubbs' type complex prepared by sol-gel co-gelification from a well-defined ruthenium alkylidene precursor bearing a silylated NHC moiety. © 2012 Elsevier B.V.
