Abstract

New neutral palladium(II) complexes having formula PdCl2(pyiuPr), PdCl2(pyiuCy), Pd(OCOCH3)2(pyiuPr), Pd(OCOCH3)2(pyiuCy), Pd(CH3)Cl(pyiuPr) and Pd(CH3)2(pyiuPr), where pyiuPr and pyiuCy are the novel ligands 1,3-diisopropyl-2-((pyridin-2-yl)methyl)isourea and 1,3-dicyclohexyl-2-((pyridin-2-yl)methyl) isourea, were synthesized and characterized. These neutral ligands act as bidentate and coordinate the palladium center through the pyridine N-atom and one of the nitrogen atoms of the isourea dent, as deducted by variable-temperature NMR experiments and DFT calculations and observed by X-ray diffraction experiments on the complex PdCl2(pyiuCy).
