| Outline of Final Research Achievements |
In this study, we have investigated copper-oxygen chemistry systematically by using a variety of supporting ligands in order to accompulish 'precise controlling of dioxygen activation by copper complexes'. The results obtained in this research are as follows.
(1) The reaction control mechanism of copper-oxygen complexes have been elucidated by using an N3- tridentate ligands and N4-tetradentate ligands having a cyclic diamine skeleton. (2) Novel copper complexes having a tetrahedral geometry have been synthesized using a newly designed N3-tridentate ligand and their structure, physiochemical properties, and reactivity have been evaluated to get deeper insights into the role of ligand structures. (3) The structural control mechanism of a copper-active oxygen complex was clarified by employing a tripod-type tetradentate ligand with a bulky substituents. (4) We achieved the ligand design aiming at the creation of a novel mononuclear copper active centers of the copper monooxygenases.
