Research Topic

The Hong group conducts research at the interface of synthetic and physical organic, inorganic, and computational chemistry with an emphasis on catalytic method development. The central objective of our lab is to establish mechanistic principles and design new reagents and catalysts that express “non-canonical” reactivity deviating from the general consensus on organic chemistry. To this end, a full range of elements in the periodic table –from main group elements to transition metals– are leveraged separately or synergistically. We apply interdisciplinary approaches based on mechanism-informed hypotheses and computer-assisted principles to delve deeper into the system of interest. Taken together, we hope to build up new conceptual frameworks and ultimately invent first-in-class molecular catalysis, enabling innovative and sustainable chemical transformations and revealing hitherto unknown opportunities in chemical synthesis.
