Highly Active Thiol-functionalized SBA-15 Supported Palladium catalyst for Sonogashira and Suzuki-Miyaura Cross-coupling Reactions

Highly ordered mesoporous silica SBA-15 with pendent 3-mercaptopropyl groups has been prepared by condensation of surface silanols and (3-mercaptopropyl)trimethoxysilane. Treatment of the mercaptopropylated SBA-15 with (CH3CN)2PdCl2 gave a heterogeneous Pd-catalyst. The immobilized Pd-catalyst se...
