| Outline of Final Research Achievements |
In this research, Ru(IV)-oxo and a unprecedented Ru(V)-imido complexes, which can act as reactive species in oxidation reactions, have been prepared and characterized. We have determined reorganization energies (lambda) of electron transfer (ET) and proton-coupled electron transfer (PCET) for Ru(IV)=O complexes for the first time to reveal that the lambda value of PCET is smaller than that of ET. We have also revealed a PCET oxidation process of a Ru(II)-NH3 complex and characterized a Ru(V)=NH complex spectroscopically. C-H oxidation by the Ru(V)=NH complex in acidic water was elucidated to involve hydride transfer from a substrate together with proton transfer from water.
