Resin encapsulated palladium nanoparticles: An efficient and robust catalyst for microwave enhanced Suzuki-Miyaura coupling

Abstract

A simple and rapid method for synthesizing highly accessible supported palladium nanoparticles inside the matrix of a commercial resin is reported. The encapsulated palladium nanoparticles were observed by TEM. The prepared catalyst has shown very high turnover frequency (TOF) in the coupling of aryl bromides with phenylboronic acid, under microwave heating. The encapsulated nanoparticles show excellent reusability and remarkable stability. The protocol is environmentally benign as no ligands, surfactants or toxic solvent were used. © 2011 Elsevier B.V.
