| Outline of Final Research Achievements |
Selective C-H functionalization of simple arenes with no directing group still remains challenges. Catalytic system utilizing substrate-ligand interaction is a powerful approach to exhibit excellent reactivity and selectivity. In the previous reports, substrate-ligand interactions are limited to hydrogen bond, pi-stacking or acid-base interaction. Therefore substrates require some functional groups. For C-H functionalization of simple arene, I herein examined cation-pi interaction between arene substrate and ligand.
I succeeded in preparing a variety of ligands having diverse linkers. Catalytic activity of these ligands was next examined in several C-H functionalization of benzene, while reactions hardly proceeded in all cases. NMR study indicated that activation ability of the ligands was little for accelerating the C-H activation process. However, during these reaction screening, novel C-H functionalization of amine was discovered.
