| Outline of Final Research Achievements |
In this study, we succeeded in the first isolation and large-scale synthesis of Mes2B+, which is a 2-coordinated boron cation (= borinium ion) bonded only with aromatic groups. This class of compound had been thought to be too unstable to isolate. By using Mes2B+, we developed a variety of unique small-molecule activation reactions including unprecedented C=O double bond cleavage reaction of carbon dioxide. Furthermore, we found that Mes2B+ serves as an excellent hole dopant for carbon nanotubes and transition metal dicarcoconide-based thin film materials. These findings will provide a foundation for a new "super Lewis acid molecule chemistry" based on isolatable super Lewis acid molecules.
