摘要：In-situ metal complexes of some 1,2,4-triazole Schiff base ligands (L 1 – L 11 ) 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 o- quinone. 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 L 10 and Cu(NO 3 ) 2 which is equal to 11.52 μmol.L -1 min -1 . Also, the solvent has huge influence on the kinetic oxidation reaction system.
