Copper(II)-coordinated organic nanotube: A novel heterogeneous catalyst for various oxidation reactions

Copper(II)-coordinated organic nanotube can function as a heterogeneous catalyst for oxidation of a variety of organic compounds in the presence of hydrogen peroxide and tert-butyl hydroperoxide. The morphology of this catalyst remained same before and after the oxidation reactions. The catalyst can be reused for several times. In the presence of hydrogen peroxide, Copper(II)-coordinated organic nanotube formed a stable brown color peroxo bridge intermediate. But such intermediate did not form with tert-butyl hydroperoxide.
