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.

制备了新型的笼形金属络合物，并将其应用于路易斯酸化学。我们的原始类型的综合体具有B（C6H4）3CH。我们将其修改为包括硅的类型。还合成了具有各种取代基（电子吸引或捐赠组）的复合物。对配合物的配体分离率进行了仔细的研究，阐明了分类为空间和电子因素的调谐因子。 DFT计算揭示了有助于刘易斯酸催化反应的Lumo能量。实际上，已经采用了一些使用复合物作为路易斯酸的有机转化。
