Research

Metal–metal multiple bonds have demonstrated fascinating chemistry. In particular, the presence of δ-bonds in quadruple and quintuple bond complexes showcases unique and unprecedented reactivities. For example, the two δ-bonds within a quintuple bond can function as surrogates for the π-bonds of alkynes, allowing them to participate in conventional organic reactions such as cycloaddition, haloacylation, and the stabilization of coordination complexes. Moreover, bimetallic cooperativity enable promising reactivity toward versatile small molecule activation, such as nitric oxides, pnictogens, chalcogens, etc. Our research is driven by a relentless pursuit to uncover the fundamental essence and reactivity of metal–metal multiple bonds.

The activation and functionalization of small molecules remain a central goal in modern chemistry. Converting harmful pollutants or inert molecules into valuable chemical feedstocks is essential for developing eco-friendly processes and advancing sustainable society. Transition metal complexes have demonstrated promising reactivity toward a wide range of inert molecules. Our goal is to develop novel transition metal systems and catalytic platforms capable of efficiently activating small molecules, such as dinitrogen, alkynes, arenes, etc.
