We are performing basic and applied studies on transformation of various organic molecules derived from petroleum and coal. The major objectives of our research group are to develop (1) new, efficient strategies for the synthesis of organic fine chemicals including pharmaceutical intermediates and π-conjugated functional materials and (2) high-performance catalysts that enable effective functionalization of organic molecules.
Our research interests involves the invention of new synthetic methodologies, with a particular emphasis on the design and development of novel catalytic system by taking advantage of unique features of transition metal complexes. A particular focus is the development of catalytic technologies for the activation and transformation of unreactive bonds, such as C-H, C-C, C-O, C-N, C-Si, C-P, and C-S Bonds.
We create functional materials that are useful for environmental protection and medical care and are friendly to humans and the environment, by using an appropriate combination of organic synthesis and molecular interactions. Currently we focus on (i) the development of molecular recognition materials that can efficiently remove harmful substances from water and oil, (ii) the development and application of micro- and nanostructures using self-organization of molecules, and (iii) the control of chiral photoreactions using weak molecular interactions.

In our laboratory, we design and create high performance materials on the basis of molecular design in consideration of developments at an industrial level for the development of three dimensional (3D) tissues for drug discovery and regeneration medicine. The extracellular matrix (ECM) is the main component of cell microenvironments in all tissues and organs. ECM regulates cell microenvironments and various cell functions. Inspired by the function of ECM, we regulate microenvironment of cell surface using novel polymer materials to control cell functions for construction of 3D-tissues with functions and structures similar to natural tissues or organs.
Our research is currently focused on designing a methodology for organic synthesis using novel organometallics and catalyst systems. Novel reactive organometallic species have been isolated and characterized based on spectroscopic methodology and X-ray crystallographic analysis. These species have been applied to the synthesis of functionalized organic compounds. Our group also focuses on utilizing characteristic Lewis acids in the conversion of carbon resources to valuable organic compounds. Metal complexes that have cage-shaped organic ligands are synthesized and used for new types of selective reactions for practical organic syntheses. We also target functionalized materials that are based on organic compounds with novel physical properties and special intramolecular interactions. All projects are supported by organic synthetic approaches that extend to various fields of chemistry.
Our research programs are focused on the development of new synthetic methods constructing carbon-carbon and carbon-heteroatom bonds by unique transition metal catalysts. We have developed anionic transition metal complexes and found their unique catalytic activities toward carbon-carbon bond formation through cleavage of unreactive chemical bonds. In addition, we are investigating on new synthetic methods to construct carbon-chalcogen and –fluorine bonds with the concomitant formation of a carbon-carbon bond and transformation of abundant carbon resources.

One of the major interests of our research is focused on the development of a transition metal-mediated selective transformation of polyfluorinated compounds such as tetrafluoroethylene (TFE). We have also been focusing on nickel-catalyzed transformation reactions via a hetero-nickelacycle intermediate as well as on their reaction mechanisms.
