Abstract

Co-polymer of 3-(2, 3-dihydroxypropyl)-1-vinylimidazolium chloride and styrene was synthesized and used as a support of Pd nanoparticles. The Pd@ poly-Sty-co-diOH-Cl catalyst can efficiently catalyze Suzuki reactions for a wide range of aryl iodides and bromides with 0.05 mol% Pd at 70° C in water–ethanol solution under air, and the catalyst can be recycled and reused for several times without significant loss of activity.
