PVC-Supported Palladium Nanoparticles: An Efficient Catalyst for Suzuki Cross-Coupling Reactions at Room Temperature

A simple and efficient protocol is described for a Suzuki reaction catalyzed by poly(vinyl chloride)-supported nanoparticles of metallic palladium at room temperature. Aryl iodides, bromides, and chlorides underwent smooth Suzuki reactions in aqueous ethanol, an environmentally friendly solvent, under ligand-free conditions to give good yields of the desired biaryl products. The heterogeneous catalyst could be used up to four times with no detectable metal leaching or loss of catalytic efficiency.
