Benign synthesis of carboxamide ligands, H2Me2bqb and H2Me2bpb. Preparation, characterization and electrochemistry of Ni(II) complexes: The crystal structure of [Ni II(Me2bqb)]

A novel and highly efficient approach for the synthesis of H 2Me2bqb and H2Me2bpb using ionic liquid as an environmentally benign reaction medium has been developed, eliminating the need for the pyridine as a toxic solvent. The Ni(II) complex of the dianionic ligand Me2bqb2-, [Me2bqb 2- = 1,2-bis(quinoline-2-carboxamide)-4,5-dimethyl-benzene dianion], has been synthesized and characterized by elemental analyses and spectroscopic methods, and the crystal and molecular structure of [Ni(Me2bqb)] (1), has been determined by X-ray crystallography. The complex exhibits distorted square-planar NiN4 coordination geometry with two short and two long Ni-N bonds (Ni-N ～1.85 and ～1.96 , respectively). The electrochemical behavior of [Ni(Me2bqb)] (1), has been studied by cyclic voltammetry and compared with the analogous complex, [Ni(Me2bpb)] (2).

New cobalt, iron and chromium catalysts based on easy-to-handle N 4-chelating ligands for the coupling reaction of epoxides with CO2

In this contribution, we report the successful utilization of several transition metal complexes based on substituted N4-N,N-bis(2- pyridinecarboxamide)-1,2-benzene chelating ligands as catalysts in the coupling of epoxides with carbon dioxide.

Steric effect on construction of Cu(II) complexes with pyridine carboxamide ligands

The structures of three new Cu(II) complexes with pyridine carboxamide ligands (Me2bpb, 6-Me2-Mebpb, and 6-Me2-Me2bpb) have been determined. 6-Methyl-substituted pyridyl bpb ligands produced dimeric compounds wi
