چکیده
|
A comparative study of new activity catecholase using complex based on three compounds type pentylidene-(4-vinylphenyl)-amine l1,butylidene-(4-vinyl-phenyl)-amine l2,sopentylidene-(4-methoxy-phenyl)-amine l3 has been reported. this study was performed to examine the catalytic effect of the in situ-generated copper (ii) complexes towards catechol oxidation reaction with atmospheric dioxygen at room temperature. all complexes catalyze the studied reaction with the rate varying from a higher 9.5625 μmol l-1min-1 for the l2[cu(ch3co2)2] to a weaker of 0.2500 μmol l-1 min-1 for l2[cu(no3)2]. the duplicating of ligand concentration influences in different way the oxidation rates. against with an excess of catechol,the oxidation rate becomes very low.
