| Outline of Final Research Achievements |
In this study, we aimed to develop heterobimetallic complexes with triazole-based carbenes as ligands and explore their catalytic functions. Specifically, we attempted to synthesize heterobimetallic complexes by generating dianions from triazolium salts with methoxycarbonyl groups through the action of t-BuOK, and then transmetallating these with transition metal salts. However, we were unable to achieve synthesis, possibly due to the instability of the bimetallic complexes. On the other hand, during the course of this study, we discovered that esters substituted with a triazolium ring exhibit extremely high reactivity, even reacting with amines at -50 ℃.

遷移金属触媒による炭素水素結合の直接官能基化はポストクロスカップリングとして近年目覚ましい発展を遂げている. 本研究では, この分子変換の有用性をさらに拡大すべく, 位置選択的な炭素水素結合を官能基化するための新規異種二核金属錯体触媒の開発を目指した. 本研究を通じて, 錯体の不安定性のためか, 異種二核金属錯体の開発には至らなかったが, 異種二核金属錯体の前駆体の調製に成功した. 本研究の成果によって, 異種二核金属錯体の安定性に関する知見が得られ, 今後は適切な金属の組み合わせを検討することで, 異種二核金属錯体の開発を目指す.
