Outline of Final Research Achievements

Oxidation reactions are widely utilized for production of chemicals and degradation of pollutants and so on. Although in most cases, it is required to oxidize only a certain position in a molecule, it is not necessarily an easy task to strictly control the selectivity of oxidation reactions. Here, the author focused on a catalyst molecule that is utilized to promote oxidation reactions, and investigated the redox properties of the catalyst molecule. The present study has shown that redox reactions readily occur on the organic moiety of the catalyst, which was previously thought to be inert for redox reactions, in addition to the transition-metal ion.
