Control of Properties of Cage-Shaped Metal Complexes

制备了新型笼形金属配合物，并将其应用于路易斯酸化学。我们最初的复合物类型是B(C6H4) 3CH。我们把它改成了含硅型。还合成了具有各种取代基（吸电子基或给电子基）的配合物。对配合物的配体解离率进行了仔细的研究，澄清了可分为空间因子和电子因子的调节因子。DFT计算揭示了参与Lewis酸催化反应的LUMO能量。事实上，一些利用配合物作为路易斯酸的有机转化已经被采用。

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.
