چکیده
|
In-situ metal complexes of some 1,2,4-triazole schiff base ligands (l1 - l11) were examined for their catalytic activities. the dioxygen complexes of metals were generated by stirring metal salts and the 1,2,4-triazoles schiff base ligands,it has been found that the oxidation of catechol is very efficient to give the appropriate oquinone. we have found that ligand structure,solvent,concentration and substrate have proven huge influence on the combinations metal/ligand reactivities. the highest rate activity is given by the in-situ complex formed by ligand l10 and cu(no3)2 which is equal to 11.52 μmol.l-1min-1. also,the solvent has huge influence on the kinetic oxidation reaction system.
