Bouanane, Zohra published the artcileSynthesis, structural, catecholase, tyrosinase and DFT studies of pyrazoloquinoxaline derivatives, Safety of 2,3-Dichloro-6-methylquinoxaline, the main research area is pyrazolylquinoxaline derivative preparation copper ligand catecholase activity; mol structure pyrazolylquinoxaline copper complex DFT; electronic structure pyrazolylquinoxaline copper complex DFT.
Six functional multidentate ligands: 2,3-bis(3,5-dimethyl-1H-pyrazol-1-yl) quinoxaline L1, 2,3-bis(3,5-dimethyl-1H-pyrazol-1-yl)-6-nitroquinoxaline L2, 2,3-bis(3,5-dimethyl-1H-pyrazol-1-yl)-6-methylquinoxaline L3, 2-(3,5-dimethyl-1H-pyrazol-1-yl)-3-hydrazinyl-6-nitroquinoxaline L4, 2-chloro-3-(3,5-dimethyl-1H-pyrazol-1-yl)-6-methylquinoxaline L5, 2-chloro-3-(3,5-dimethyl-1H-pyrazol-1-yl)quinoxaline L6, (I – VI) and a new copper (II) complex (VII) , were prepared and evaluated for their catecholase activities at aerobic conditions. We found that, the reaction rate depends on: the nature of the substituents in the quinoxaline ring, counter anion, metal, concentration of ligand and the used solvent. The complex obtained in-situ from reaction of one equivalent of ligand L1 and two equivalent of Cu(CH3COO)2 in methanol showed the highest oxidation rate activity (V = 33.48 μmol L-1. min-1). In addition, geometry optimizations of the complexes in order to get better insight into the geometry and the electronic structure and chem. reactivity were carried out by means of DFT calculations
Journal of Molecular Structure published new progress about Counterions (counterion effect on catecholase activity). 39267-05-5 belongs to class quinoxaline, name is 2,3-Dichloro-6-methylquinoxaline, and the molecular formula is C9H6Cl2N2, Safety of 2,3-Dichloro-6-methylquinoxaline.
