Copper Co-ordination Chemistry of some Quadridentate Pyridazine and Phthalazine (N4) Thioether Ligands. Binuclear Copper(II) Complexes exhibiting Two-electron Reduction at Positive Potentials

Binuclear, hydroxo-bridged, copper(II) complexes of a series of quadridentate pyridazine and phthalazine thioether ligands involving nitrogen donor groups (derived from pyridine, imidazole, benzimidazole) exhibit room-temperature magnetic moments in the range 1.1-1.7 B.M., indicative of antiferromagnetically coupled binuclear copper(II) centres.Cyclic voltammetry and coulometry on most of these systems indicate reversible or quasi-reversible redox processes, involving two-electron transfer, at positive potentials (0.23-0.49 V vs. a saturated calomel electrode in CH3CN or dimethylformamide).Mononuclear copper(II) derivatives, involving bidentate ligands, also exhibit reduction at positive potentials.Catecholase activity involving 3,5-di-t-butylbenzene-1,2-diol has been demonstrated for the hydroxo-bridged complex *EtOH , in which a Michaelis-Menten kinetic treatment gave KM=3.4*10-4 mol*dm-3 and a value of kp=2.1*10-2 s-1 for the dissociation of the catechol-complex intermediate.

Electronic and Photophysical Properties of ReI(CO)3Br Complexes Modulated by Pyrazolyl-Pyridazine Ligands

The direct reaction of a series of substituted (1H-pyrazol-1-yl)pyridazine (LI: 6-(1H-pyrazolyl)pyridazine; LII: 3-chloro-6-(1H-pyrazole-1-yl)-pyridazine; LIII: 6-(1H-3,5-dimethylpyrazolyl)pyridazine-3-carboxylic acid; LIV: 3,6-bis-N-pyrazolyl-pyridazine; and LV: 3,6-bis-N-3-methylpyrazolyl-pyridazine) with the bromotricarbonyl(tetrahydrofuran)-rhenium(I) dimer leads to the monometallic complexes [(LX)Re(CO)3Br] (I-V), which displays a nonregular octahedral geometry around the ReI center and a fac-isomerism for the carbonyl groups, whereas pyridazine and pyrazolyl rings remain highly coplanar after coordination to rhenium. Cyclic voltammetry shows one irreversible oxidation and one irreversible reduction for each compound as measured in N,N-dimethylformamide. Oxidation ranges from 0.94 V for III to 1.04 V for I and have been attributed to the ReI/ReII couple. In contrast, the reductions are ligand centered, ranging from -1.64 V for II to -1.90 V for III and V. Density functional theory calculations on the vertical one electron oxidized and one electron reduced species, using the gas-phase optimized geometry for the neutral complex confirm this assignment. Compounds I-V show two absorption bands, one around 410 nm (metal-to-ligand charge transfer (MLCT), Redpi ? pi?) and the other at ?300 nm (intraligand, pi ? pi?). Excitation at 400 nm at 77 K leads to unstructured and monoexponential emission with large Stokes shift, whose maxima vary between 570 (III) and 636 (II) nm. The quantum yields for these emissions in solution are intensified strongly going from air to argon equilibrated solution. Singlet oxygen quantum yields change from 0.03 (III) to 0.21 (IV). These data are consistent with emission from 3MLCT. The emission undergoes a bathochromic shift when R1 is a pi-donating group (Cl or N-pyrazolyl) and a hypsochromic shift for a pi-acceptor (COOH). The bimolecular emission quenching rate constant by triethylamine (TEA) for II, IV, and V is 1.09, 0.745, and 0.583 ¡Á 108 M-1 s-1, respectively. Photolysis in dichloromethane-CO2 saturated solution with TEA as a sacrificial electron donor leads in all cases to formic acid generation.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 2164-61-6 is helpful to your research. Synthetic Route of 2164-61-6
