It was instrumentally characterized by elemental analyses, IR, UV-VIS, XPS and ESR spectroscopy. It was demonstrated that the immobilization of Cosalen was realized through the coordination of the amino group in Chitosan with the Co (Ⅱ) in the CoSalen complex. It binds molecular oxygen reversibly in the solid state through the vacant sixth coordination site.展开更多

Compound (2) forms complex with copper ion to give compound (3), the catalytic activity of which for the oxidation of propanethiol was examined.The chemical structures of compounds relating to salen were identified by IR spectra as well as elemental analysis. The composition of the oxidation product was also identified by HPLC, UV, IR and MS.展开更多
