Research Interest:

Organometallic: Transition Metal-catalyzed Nitrogenation of Hydrocarbons. We discovered that Cu-salts and related complexes catalyze olefins with arylhydroxylamine to produce allyl amines. The reactions occur with remarkable regioselectivity with respect to the alkene and the products are valuable as synthetic intermediates and bioactive targets. Most recently, we discovered asymmetric allylic mination catalyzed by Cu.

Medicinal Inorganic Chemistry: Ruthenium-based Metallopharmaceuticals Primarily we are tackling problems related to the synthesis of ruthenium complexes with various heterocyclic amines and their assay on various cancer cell-lines. Another area of development in medicinal inorganic chemistry is the development of ruthenium-based anticancer drugs and strategy to overcome drug resistance.

Renewable Biomass Energy: Metal-catalyzed Conversion of Cellulosic Biomass for fuels and value-added chemicals We aim to develop new more robust and economically viable catalytic systems for efficient, selective, economical deoxydehydration reactions of cellulosic biomass. Reactivity studies will test the effectiveness of the new reductants and catalysts, identify and quantify the reaction products, and use this information to develop new processes for valuable products and fuels.
