Title

Functionalization of mesoporous silicas as powders for support and immobilization of Pd catalysts and as monolithic framework for building strong lightweight materials

Keywords and Phrases

Sonogashira coupling

Abstract

"Immobilization of catalysts is a promising approach to combine the advantages of heterogeneous and homogeneous catalysts. Pd(PPh₃)₂Cl₂ known as an extremely active homogeneous catalyst for the Sonogashira coupling reaction has been immobilized on high surface area MCF (mesocellular foams)-type mesoporous silica powder modified with 3-aminopropyltriethoxysilane (APTES). The functionalized MCF-type silica and supported catalysts have been characterized by FTIR, BET, and Elemental Analysis. Such supported Pd catalysts have proven to be useful reagents for copper-, and amine-free Sonogashira reactions for the coupling of haloaromatic compounds and alkynes"--Abstract, leaf iv.
