| Outline of Final Research Achievements |
A newly designed quinoline-based multidentate phosphine ligand was synthesized and examined for complexation with various transition metal species directed toward selective formation of a dinuclear metal complex with metal-metal bonding, which could be potentially useful catalyst in organic synthesis. Complexation of the ligand with platinum(II) was well-controlled by modifying substituent on the platinum center to afford mononuclear and dinuclear complex selectively. X-ray crystallographic structure analysis and computational studies based on quantum chemistry disclosed the working hypothesis of the design of the new ligand.

| Academic Significance and Societal Importance of the Research Achievements |
現代の豊かさを支える分子合成手法の開発に大きく貢献可能な遷移金属錯体触媒の開発は，適切な配位子の設計に依るところが極めて大きい．単純な単核錯体と異なり，二核以上の錯体を選択的に合成するための配位子設計として，本研究ではホスフィン部位を2つ有するキノリン分子の構造に由来する特異な配位性が有効であることを示した．有用な触媒反応開発には至らなかったが，新しく有効な配位子設計指針を示すことに成功しており，この知見を元にさらに精密な錯体合成法の開発，および新規錯体触媒開発につながる一助になると期待される．
