Palladium(II) complexes bearing bidentate pyridyl-sulfonamide ligands: Synthesis and catalytic applications
Özet
New palladium(II) complexes aPd(1-5)(2)], 6-10, (1-5 = bidentate pyridyl-sulfonamide ligands)) were obtained from the reaction between Pd(OAc)(2) and bidentate pyridyl-sulfonamide ligands. The synthesized compounds were characterized by elemental analysis, TG, NMR, IR and X-ray diffraction. The Pd(II) complexes 6-10 were investigated as catalysts for the oxidation of benzyl alcohol to benzaldehyde in the presence of periodic acid as the oxidant and acetonitrile as the solvent under reflux. All the complexes were moderately active catalysts for the catalytic reaction (the oxidation of benzyl alcohol to benzaldehyde), with good yields under mild conditions. (C) 2014 Elsevier Ltd.
