Research Interest

Our research principally focuses on the development of novel molecules containing p-block elements, especially boron, silicon and phosphorus, and it spans the fields among organic, inorganic, and organometallic chemistry. By taking advantage of characteristic properties of p-block elements, we design and synthesize fundamentally significant and interesting compounds featuring unique bonds and structures. Since the peculiar design of our molecules gives rise to original properties, they are not limited to be only laboratory curiosity, but will have important applications such as building blocks, organocatalysts, ligands, etc. Our research directions are outlined as follows:

1. Novel Bonding and Structural Paradigms.
We search for new types of bonding and structural paradigms which are hitherto unknown in classical organic and inorganic chemistry. In particular, multiply bonded compounds including boron as well as heavier main group elements have potentials to be useful synthetic building blocks to produce new inorganic compounds just like alkenes and alkynes in organic synthesis. Such approach will allow for the preparation of new materials previously inaccessible by conventional methods.

2. Stable Version of Transient Species.
Reactive intermediates have proven to play a central role in fundamental research. If it is possible to control and use such species at will, many fields in chemistry would progress dramatically. Based on our long-standing experience in the stabilization of highly reactive species, we develop isolable low valent elements which are supposed to be only transient intermediates, such as borylenes, vinylidenes, nitrenes, radicals, heterocycles, and their heavier group elements analogous.

3. Organic and Organometallic Catalysis.
Efficient and selective synthesis of organic molecules is of paramount significance in industry. It is critical for our future to find powerful catalysts enable selective conversion of abundant molecules into industrially important compounds such as bulk chemicals, in low energy demand processes. Using our original molecules as organocatalysts or ligands for transition metal complexes, we develop efficient catalytic systems which will not only solve industrial production issues as the selective synthesis of materials, but also allow for reducing considerably the cost of chemical processes

Overall objective of our research is directed to establish a novel fundamental chemistry, which can be applied to new materials in catalysis and synthetic chemistry. By demonstrating such concept, one of the ultimate goals of our research effort is the development of green and sustainable chemistry approached by inorganic and organometallic chemistry, which consequently will address current world-wide issue such as energy conservation and environmental impacts
