About Me

Our research group is interested in the development of pincer ligand-based organometallic catalysts for small organic molecule activation as well as for various organic transformation through C-H bond activation. Our work involves activation and catalytic functionalizations (alkylations, fluorinations, carboxylations, etc.) of relatively inert C-H bond using inexpensive organometallic complexes of Cobalt, Nickel and Copper salt. Our focus is on the mechanistic-based approach for the development of new catalysts.
