A series of polymeric amine-palladium(0) complexes have been prepared from organic silica via immobilization on fumed silica, followed by treatment with palladium chloride in ethanol and then the reduction with KBH4 in ethanol. The effects of amine ligands and solvent on catalytic properties of silica supported amine-palladium(0) complexes were studied. They are efficient catalysts for Heck arylation of aryl iodides with alkene and can be recovered and reused. (C) 2003 Published by Elsevier B.V.
