The creation of "new chemical species" that do not exist in conventional contexts allows for the simultaneous elucidation of new properties such as bonding, structure, and reactivity, as well as the clarification of the new reactivity they confer. In particular, composite compounds that combine main group elements and transition metals generate unique "elemental characteristics" between the elements, enabling the creation of highly active catalysts and highly reactive chemical species. As examples of such "elemental characteristics," we have worked on (1) the development of precision olefin polymerization catalysts and (2) the synthesis of low-coordinate compounds of high-period group 14 elements (tetrelens). In (1), we achieved high activity that surpasses conventional catalysts and successfully produced polyolefins with controlled stereostructures. In (2), the synthesized tetrelens exhibited unique coordination behavior towards transition metals and were found to be usable as alternatives to rare transition metal catalysts. Currently, we are challenging the development of catalysts that enable the conversion reactions of carbon dioxide into useful chemical products using tetrelens.
