Studies of Catecholase Activities of N-donor Bidentates Ligands derivated from Benzoxazole with Copper (II) Salts

Abstract : Three functional, N-donorbidentates ligands, L1 2-(pyridin-2-yl) benzoxazole L2 2-(quinolin-2-yl) benzoxazole and L3 2-(4-(trifluoromethyl) pyridin-2-yl) benzoxazole have been examined for their catalytic oxidative activities. The dioxygen complexes of Cu(II) were generated in situ by stirring copper salts and bidentates ligands derivated from benzoxazole. It has been found that these compounds are very efficient to give oquinone. The nature of the ligands, the counter anion copper (II) salts and solvent have been investigated. These three parameters have an important effect on the oxidation reaction rate.
