Overview of Research
Our laboratory focuses on organometallic chemistry. We studies preparations, properties, reactions, and applications of various transition metal complexes as well as their ligands.
One of our research areas is a development of bio-inspired large ligand systems, which contain sequence-defined side chains: In our ‘linked (ethynylthienyl)oligoarene system’, various side chains can be introduced in a defined order.
Another area of research is the study of labile tungsten and molybdenum complexes, showing high reactivity toward various reagents.
The third area is the development of new methods for determining the absolute configuration of organic compounds, using lanthanoid metal-containing chiral NMR shift reagents.
