About the Research

Research Theme

Development of new catalytic reactions using transition metals


Organometallic chemistry

Research Outline

My research is on the development of super-efficient and powerful catalysts and chemical reactions through ligand design. The ligand is the molecule that binds to a metal, thus dramatically changing the property of a metal. Fascinated by the very beautiful molecular structure of biological enzymes, I aim to synthesise such a catalyst by the combination of rather simple molecules, rather than preparing very complex and big molecules paying a large synthetic cost.

My work relates to two important trends and demands in my field. One is the utilization of unreactive chemical bonds, for example the unactivated C-H bond, to produce molecular complexity. The other is the asymmetric synthesis of chiral molecules from simple achiral molecules that is important for pharmaceutical science.

The Researcher’s Perspective

Since having become a professional scientist, I like to think that I have become much better at writing, at least in the Japanese language. The necessity to explain my work and its importance to other people in written but also in spoken form gave me an opportunity to grow my abilities in this respect.
