Palladium supported on polyether-functionalized mesoporous silica. Synthesis and application as catalyst for Heck coupling reaction

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 (M-w = 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. Copyright (C) 2009 John Wiley & Sons, Ltd.
