Outline of Final Research Achievements |
Nickel-catalyzed C-H bond activation reactions developed to date have required the use of bidentate directing groups. However, based on the elucidation of the reaction mechanism, including DFT calculations, it was found that the reaction proceeds even with a simple amide directing group when a strong base is used. Based on this finding, we have found that this strategy is applicable to the activation of various unreactive bonds, such as C-F bond, C-O bond, C-S bond, and C-CN bonds. Furthermore, C-H bond activation reactions using acylimidazole as a directing group and iridium complexes as catalysts were found. We also succeeded in developing transition metal-free C-H borylation of aromatic aldehydes using an imine as a transient directing group. We also succeeded in developing catalytic reactions involving both C-H and C-C bonds.

Academic Significance and Societal Importance of the Research Achievements |
従来の有機合成化学は、反応性の高い結合を利用してきた。もし、今まで有機合成反応にほとんど利用されてこなかった不活性な化学結合を有機合成化学に使うことができれば、有機合成化学における方法論を多様化させ、合成手法の革新的発展につながる。その結果として、医農薬、天然物、機能性有機材料、高分子材料の合成など、物質を必要とする周辺分野にも大きな影響を与えることが期待される。カーボンニュートラル、グリーンイノベーションの進展にも大きく寄与する研究である。
