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

Abstract

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 ( 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 © 2009 John Wiley & Sons, Ltd.
