In recent years, converting molecules into desired products and synthesizing functional molecules become more important from a viewpoint of establishing the recycling-based society. Our main research aims include 1) development of innovative synthetic processes utilizing common metal elements, 2) molecular design and synthesis toward understanding biological functions such as photosynthesis, and 3) theoretical analysis of reaction mechanisms. We are conducting cutting-edge multidisciplinary research that combines synthetic organic chemistry, spectroscopy, and computational chemistry.
