Magnetic dendritic polymer nanocomposites as supports for Palladium: a highly efficient and reusable catalyst for Mizoroki-Heck and Suzuki-Miyaura coupling reactions

Abstract

A novel catalyst Fe3O4@SiO2-Dendrimer-Pd based on palladium immobilized on magnetic dendritic polymer nanocomposites was successfully synthesized and characterized by FT-IR, EA, XRD, TEM, EDX, VSM and XPS. This nanocatalyst showed excellent catalytic activity for solvent-free Heck reaction and Suzuki-Miyaura reaction in EtOH/H2O at palladium loading of only 0.009 mol%. Moreover, Fe3O4@SiO2-Dendrimer-Pd catalyst could be conveniently recovered by an external magnet and used consecutively for five times with excellent yields achieved. The remarkable catalytic performances and convenient magnetic separability of the Fe3O4@SiO2-Dendrimer-Pd catalyst make it a promising catalyst for the practical application.
