Abstract

Bulky 2,6-dibenzhydryl-4-methylaniline reacts with 2-hydroxybenzaldehyde or 2-pyridinecaboxyaldehyde to form [N,O-] and [N,N] donor ligands, 2-(((2,6-dibenzhydryl-4-methylphenyl)imino)methyl)phenol (L1) and N-(2,6-dibenzhydryl-4-methylphenyl)-1-(pyridin-2-yl)methanimine (L2), respectively. Schiff bases, L1 and L2 on treatment with metal precursors, MCl2 (M = Pd, Cu or Co) in toluene under reflux conditions afford mono- or dinuclear complexes [(L1-H)2M] (M= Pd (1) and Cu (2)) or [L2(μ-Cl)M]2 (M= Cu (3) and Co (4)). The ligands and complexes were structurally characterized through single crystal X-ray diffraction and depending upon the type of compound, further characterized by spectroscopic (IR, Mass, NMR, EPR, UV-Vis), mircroanalytical (CHN), thermal (TGA) and electrochemical (CV) techniques. Complex 1 was employed in Suzuki-Miyaura coupling whereas complexes 2-4 were studied for the oxidation of secondary alcohols. These were found to be efficient catalysts for the respective reaction systems.
