摘要：

A series of novel binuclear Pd(II) complexes of the type [(PPh3)(2)ClPd(L)PdCI] [where L = dianionic bridged ligands derived from 2-oxo-1,2-dihydroquinoline-3-carbaldehyde or its derivatives with o-aminophenol/o-aminothiophenol] have been reported. The new complexes have been characterized by elemental analysis, FT-IR, UV-Vis and NMR (H-1 and P-31) spectroscopic techniques. The coordination mode of the ligands and the geometry of the complexes were confirmed by single crystal X-ray crystallography of one of the complexes. The catalytic efficiency of one of the binuclear Pd(II) complexes was tested for N-arylation of imidazole. (C) 2011 Elsevier Ltd. All rights reserved.
