Abstract
The synthesis of a palladium complex and a monosilylated monomer derived from 15-membered azatriolefinic macrocycle are described as well as the preparation of the corresponding hybrid organic-inorganic materials, containing a macrocyclic palladium(0) complex covalently anchored to the silica matrix. The materials were obtained by sol-gel process using different routes: post-synthesis treatment on a mesostructured silica, cogelification of a monosilylated precursor and tetraethylorthosilicate. The activity of the different materials as recoverable catalysts in Suzuki cross-couplings is reported and commented. © 2007 Elsevier B.V. All rights reserved.
