Abstract
A new catalytic system based on Pd supported on polyether-functionalized mesoporous silica was prepared. This material was obtained by co-hydrolysis and polycondensation of tetraethylorthosilicate and a bis-silylated triblock copolymer P123 (Mw = 5800) followed by the decomposition of Pd(OAc)2 salt. We have shown that this material can be applied as powerful heterogeneous catalyst for the Heck coupling reaction.
