Water-soluble 2-aryinaphthoxazole-derived palladium (II) complexes as phosphine-free catalysts for the Suzuki reaction in aqueous solvent

Two water-soluble palladium (II) complexes 2 and 4 have been synthesized from easily available 2-arylnaphthoxazole derivatives. They were successfully applied to the Suzuki coupling of aryl bromides with phenylboronic acid in water at 100 degrees C under phosphine-free conditions. Copyright (C) 2008 John Wiley & Sons, Ltd.
