| Outline of Final Research Achievements |
The strategy of intramolecular metallacyclization may facilitate the development of organo-hydride chemistry like a coenzyme NADH. In this study, we synthesized novel ruthenium complexes bearing both carbonyls (CO) and naphthyridine derivatives (pynp or paa). We examined redox properties of the complexes using electrochemical and spectroelectrochemical measurements. Chemical reduction of the pynp complex with a reducing agent led to formations of organo-hydride species caused by metallacyclization in addition to conventional metal-hydride one. On the other hand, the corresponding paa complex changed to a “hybrid” compound which involved both metal-hydride and organo-hydride moieties. A hydride transfer reaction between the hybrid hydride-complex and a hydride acceptor was confirmed experimentally.
