The orthopalladation dinuclear [Pd(L1)(μ-OAc)]2, [Pd(L2)(μ-OAc)]2 and mononuclear [Pd(L3)2] complexes with [N, C, O] or [N, O] containing ligands: Synthesis, spectral characterization, electrochemistry and catalytic properties

We described the synthesis of the five new salicylaldimine ligands and their orthopalladation dinuclear [Pd(L1)(μ-OAc)]2, [Pd(L2)(μ-OAc)]2 and mononuclear [Pd(L3)2] metal complexes. The compounds have been identified by a combination of 1H and 13C NMR spectra, FT-IR spectra, UV-Vis spectra, elemental analysis, molar conductivity measurements, and electrochemical techniques. The Pd(II) complexes exhibited catalytic activity in Suzuki-Miyoura coupling reactions and the hydrogenation of nitrobenzene and cyclohexene.
