Across the Board: Yang Li on Visible‐Light Photoredox Catalysis

Abstract

In this series of articles, the board members of ChemSusChem discussrecent research articles that they consider of exceptional quality and importance for sustainability.T his entry features Prof. Y. Li, who discusses visible-light photoredox catalysis by acridinium photocatalysts, which show both powerful oxidative and reductive abilities. She also highlights the mechanism for generation of an eutral acridine radical and its application in the reduction of aryl halides. Scheme1.Importanta cridinium photocatalysts and the redox potentials. Scheme2.Proposed mechanism for the dehalogenation.
