Poly(vinyl chloride)-supported nanoparticles of metallic palladium enable an efficient Suzuki reaction at room temperature. Aryl iodides, bromides, and chlorides underwent smooth reactions in aqueous ethanol 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.
