Synthesis, crystal structure, and electrocatalytic properties of a copper(II) complex of 1,2-bis(2-benzimidazolyl)benzene

A new copper(II) complex based on the rigid ligand OBimB (OBimB = 1,2-bis(2-benzimidazolyl)benzene) has been synthesized and structurally characterized by X-ray single-crystal diffraction. In the structure of the complex, each Cu(II) atom is coordinated by four N atoms from two twisted V-shaped OBimB ligands in a square-planar geometry. The complex has been used as a bulk modifier to fabricate a carbon paste electrode (Cu-CPE). Electrochemical studies of the Cu-CPE in 0.1 M pH 2.0 phosphate buffer solution reveal that the Cu2+/Cu+ redox process is quasi-reversible. Electrocatalytic studies of the Cu-CPE indicate that it has good electrocatalytic activities toward reduction of bromate, hydrogen peroxide, and nitrite.

Synthesis, characterization and catecholase biomimetic activity of novel cobalt(II), copper(II), and iron(II) complexes bearing phenylene-bis-benzimidazole ligand

Transition metal complexes of Co(II), Cu(II), and Fe(II) bearing a rigid symmetrical 2,2′-(1,2-phenylene)bis(1H-benzimidazole) ligand, PhBIm2, were synthesized and fully characterized by ESI-MS, FT-IR, 1H NMR (for paramagnetic species), UV–Vis spectroscopy and microanalytical techniques. Besides the cobalt complex was subject of X-ray structural analysis. The molecular crystal structure of the PhBIm2Co(II)Cl2 complex revealed the metal center in a pseudo-tetrahedral environment with not significant lengthening or compressing of the bonds in the PhBIm2 framework upon chelation of the ligand. All complexes catalyze the aerobic oxidation of o-catechol to o-quinone under mild conditions. The results show that the oxidation rate depends on the electronic stabilizing effect to the metal center rather than the steric hindrance of the ligand. Kinetic parameters (Vmax, kcat, KM) were estimated by mean of the Michaelis–Menten model and Lineweaver–Burk plot. Catechol oxidation rates of complexes 2–4 are in the same order of magnitudes of mononuclear and dinuclear Cu(II) complexes bearing imidazole-based ligands but lower than observed for the catecholase enzyme.

Ti (IV) complexes of some heterocyclic ligands synthesis, characterization and ethylene polymerization activity

31 complexes of bis - (benzimidazole, benzothiazole and benzoxazole) compounds with Ti (IV) metal centers were synthesized, characterized, activated with methylalumoxane (MAO) and then tested for catalytic ethylene polymerization. The activities of the various catalysts were found to be functions of the hetero atoms in the ligand frameworks. The highest activity was obtained with 39/MAO (573 kg PE/mol cat. h). The produced polyethylenes showed high molecular weights (up to 1.5 × 106 g/mol) and broad molecular weight distributions (PD = 65). This could result from different interactions of the MAO counterion with the heteroatoms of the catalyst ligand generating different active sites.
