A series of new ionic binuclear Pd(II) complexes supported by water-soluble bis(-diimine) ligands were prepared and employed as catalysts for the palladium-catalyzed Suzuki reaction in aqueous media. The binuclear nature of the complexes increased the reaction rate, while electronic and steric modification of the ligand frameworks had a remarkable influence upon the catalytic activity of the palladium complexes. The catalysts were shown to be homogeneous through mercury poisoning experiments and complexes could be recycled more than 10 times without loss of catalytic activity.
