“…Chakraborty et al have previously noted the differences in the reaction rates of complexes with 3,5-DTBC depending on the solvent used -acetonitrile or DMSO. 19 A similar observation is herein made; a higher catecholase activity (i.e. k cat = 2.06 ± 0.09 h -1 ) is observed in methanol compared to 1.51 ± 0.08 h -1 observed in DMF.These values are rather low compared to those for Cu(II) in the literature.…”

“…16,17 Compartmental Schiff bases, obtained by the condensation of salicylaldehyde or salicylaldehyde derivatives with diamines, have two cavities of different dimensions. [18][19][20][21][22] Thus, these types of ligands can bind with one or two metal centers, enabling the successful synthesis of homo-and/or heteronuclear metal complexes with interesting stereochemistry. 20,[23][24][25] Complexes derived from compartmental ligands have been widely studied over the last decades especially due to their applications as models of different metalloproteins.…”

“…1,4,10,11 Model complexes have played an important role in understanding the structural, spectroscopic and catalytic properties of the copper sites in protiens. [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26] Various workers have tried to rationalize the catalytic efficiency of the catechol oxidation reaction with variety of parameters like redox potentials, solvent effect, pH of the medium, number and nature of bridging ligands, effect of secondary coordination sphere etc., however our knowledge in this direction is still sketchy and incomplete. 12,13,[17][18][19][20][21][22][23][24][25][26] Therefore, there is need for study of new model complexes showing catecholase activity and exploration of relationship between their structural, spectroscopic and catalytic properties.…”
