Synthetic organic chemistry undertakes significant efforts to develop new catalytic transformations that utilize greener reagents and avoid stoichiometric additives. In this regard, visible-light photoredox catalysis offers a unique activation mode of molecules, which serves as an alternative to many thermal transition-metals catalyzed reactions. Most photoredoxcatalyzed processes capitalize on heavy metals, namely, Ru(II) or Ir(III)-complexes, which can serve as single electron oxidants or reductants in their photoexcited states. Copper-and iron-based photocatalysts are rapidly emerging, offering not only economic and ecologic advantages but in addition, can interact with substrates beyond electron transfer via inner sphere mechanisms. Emphasizing the principles of inner sphere photoredox catalyzed processes, selected synthetic applications from our laboratory will be discussed, highlighting the opportunities copper- and iron-photocatalysts offer.
Bio of Prof. Oliver Reiser：
Oliver Reiser studied chemistry at the Universities of Hamburg, Jerusalem, and Los Angeles (UCLA) and obtained his Ph.D. in 1989 with Prof. Dr. Armin de Meijere. He spent 2.5 years as a postdoctoral fellow with Dr. R. Miller, IBM Research Center, San Jose, USA, and with Prof. Dr. D. A. Evans, Harvard University, Cambridge, USA. In 1992 he moved to the University of Göttingen as an Assistant Professor, and in 1996 he moved to the University of Stuttgart as an Associate Professor. Since 1997 he has been a Professor of Organic Chemistry at the University of Regensburg, having served as Vice President and currently as Dean responsible for Research. His group’s research interests are focused on developing sustainable methodologies for converting renewable resources towards value-added compounds.
