| Outline of Final Research Achievements |
In order to develop novel catalytic systems that can convert stable chemical bonds and molecules efficiently, this research aimed at development of highly oxidized/reduced transition metal catalysts upon visible light irradiation by using π-conjugated ionic molecules as ligands. As a result, several Pd complexes with an acridine ligand showed a distinct reactivity under photo-irradiation and were applied to cross-coupling reactions.

| Academic Significance and Societal Importance of the Research Achievements |
有機合成化学では近年、天然に豊富に存在する安定で不活性な分子（窒素や二酸化炭素）や結合（C-H, C-C結合）を温和な条件で効率的に化学変換する手法の開発が望まれている。本研究では、イオン性の有機分子を利用することで、光エネルギーにより遷移金属触媒の酸化力・還元力を向上させる新たな方法論の構築に取り組んだ。目的とする安定分子の活性化には至っていないものの、新たな触媒設計・反応性に関する知見が得られており、今後の発展が望まれる。
