Recent Advances in Fe-Catalyzed Radical Cascades/Cross-Couplings

Presented by Prof. Osvaldo Gutierrez, Texas A&M University


Despite advances in high-throughput screening methods leading to a surge in the discovery of catalytic reactions, our knowledge of the molecular-level interactions in the rate- and selectivity-determining steps of catalytic reactions, especially those involving highly unstable and reactive open-shell intermediates, is rudimentary. These knowledge gaps prevent control, suppression or enhancement, of competing reaction channels that can drive development of unprecedented catalytic reactions. In this talk, I will focus on our use of high-level quantum mechanical calculations, rigorously calibrated against experimental data, to interrogate the mechanisms and to guide the development of new catalysts and reagents for currently sluggish or unselective reactions. In particular, I will focus on our use of combined experimental and computational tools to understand and develop new (asymmetric) three-component iron-catalyzed radical cascade/cross-coupling reactions.

Osvaldo was born in Mexico and raised in Sacramento, California. He attended Sacramento City College and transferred to UCLA in 2006 where he worked as an undergraduate at the laboratories of Prof. Houk. He obtained his B.S./M.S. in 2009 and completed his Ph.D. in 2012 (UC Davis) under the guidance of Prof. Tantillo. From 2012-2016 he worked as a postdoc with Prof. Kozlowski at the University of Pennsylvania where he used computational and experimental tools to study transition metal-catalyzed processes. In 2016 he started his independent position at the University of Maryland College Park as an Assistant Professor, and then Associate Professor until 2021. In the Summer 2021, he moved to Texas A&M University where his research combined computational and experimental approaches to advance our understanding of iron- and photo-catalyzed reaction mechanisms.
