A magnetic nanoparticle-supported di(2-pyridyl)methanol palladium dichloride complex was prepared via click chemistry. This complex is a highly efficient supported catalyst for Suzuki coupling reaction using aryl bromides as substrates and can easily be separated by an external magnet and reused in five consecutive runs without obvious loss of activity.
