| Research Abstract |
New type of cage-shaped metal complexes were prepared and applied to Lewis acid chemistry. Our original type of the complex has B(C6H4) 3CH. We modified it to silicon-including type. The complexes with various substituents(electron-withdrawing or donating groups) has been also synthesized. A careful investigation of ligand-dissociation rate on the complexes clarified the tuning factor that is classified into steric and electronic factors. DFT calculation revealed the LUMO energies that contribute to Lewis acid-catalyzed reactions. In fact, some organic transformations using the complexes as a Lewis acid have been employed.
