Mesoporous Silica MCM-41 Supported N-Heterocyclic Carbene-Pd Complex for Heck and Sonogashira Coupling Reactions

Mesoporous Silica MCM-41 Supported N-Heterocyclic Carbene-Pd Complex for Heck and Sonogashira Coupling Reactions

Heterocyclic carbene-Pd complex was anchored onto themesoporous silicaMCM-41 which exhibits high catalytic activity in Heck reaction under phosphine free reaction conditions for the reaction of iodo/bromoarenes with olefinic compounds such as butyl acrylate, isopropyl acrylate and styrene. This ca...
