Visible light photoredox catalysis enables challenging organic transformations to be carried out under mild reaction conditions. However, the applicability of photoredox catalysis has been hampered due to the limited scalability. Our group has been engaged in developing novel photocatalytic methods to enable C–CF3, S–CF3, C–S and S–S bond forming reactions. A substantial acceleration is observed when this chemistry is translated to continuous-flow: from hours/days in batch to seconds/minutes in flow.
