----------
Dr. David Nicewicz from the University of North Carolina at Chapel Hill will be presenting this weeks seminar titled New Avenues in Synthesis via Organic Photoredox Catalysis.

 

Abstract: Single electron pathways are prevalent in numerous biosynthetic pathways that are crucial to life on our planet. As synthetic chemists, we seek to harness the power of these open-shell processes to achieve uncommon but valuable chemical reactivity. To this end, my laboratory is interested in accessing single electron pathways via the use of organic photoredox catalysis. This lecture will highlight the recent synthetic methods developed by my laboratory, including anti-Markovnikov hydrofunctionalizations of alkenes and polar-radical crossover cycloaddition reactions.  Mechanistic tools such as time resolved and steady state absorption spectroscopy shed light on the mechanism and will be presented in the lecture. More recent developments will highlight the use of organic photoredox catalysis in direct C-H functionalization reactions of aromatic compounds.
