Executive Summary
Dr. Dhar specializes in the mechanistic studies of inorganic, organic and enzymetic reactions. His recent research work mainly focused on sustainable and green chemistry. He wants to develop heterogeneous and homogeneous oxidation catalysis for various organic transformations using first row elements, thereby minimizing the use of rare metals as catalysts in synthetic chemistry. A recent highlight of his research has been first ever quantitative formation of a Fev(O) reactive intermediate species at room temperature and study of its reactivity towards various organic transformations like hydroxylation of unactivated C-H bond. He has already published more than 27 research papers in peer reviewed scientific journals. From 2011 to 2015, he worked as a pool scientist in CSIR-National Chemical Laboratory, Pune.
