摘要: Novel Co(Ⅱ) complexes with dihydroxamic acids functionalized N-pivot lariat ether CoL¹-CoL⁴ were synthesized and characterized. Their oxygenation constants (ln K_O2) and thermodynamic parameters (ΔH°, ΔS°) were measured. And their catalytic performance in oxidation of p-xylene to p-toluic acid (PTA) was investigated. The enhancement of O₂-binding and catalytic oxidation activity by the oxa aza crown ether ring of the cobalt complexes were discussed.
