Three cyclopalladated 6-bromo-2-ferrocenylquinoline complexes with NHCs and PPh3 1-3 have been synthesized and characterized by elemental analysis, IR, NMR and single-crystal X-ray diffraction. Their application to Suzuki coupling of phenylboronic acid containing hydroxymethyl was also investigated. An efficient 3/Cu cocatalyzed oxidation/Suzuki coupling of aryl chlorides with phenylboronic acids containing hydroxymethyl in air has been developed. (C) 2014 Elsevier B.V. All rights reserved.
