Photocascade Catalysis: A New Strategy for Cascade Reactions

This Concept article highlights recent advances in the rapidly developing field of visible-light-driven, single-photocatalyst-promoted photocascade catalysis and its application in the discovery of novel reactivities suitable for cascade reactions. Examples of photocascade catalytic transformations are categorized by the activation modes of substrates and intermediates involved in these processes. It is hoped that this emerging catalysis strategy will enable chemists to develop many more useful, sustainable and sophisticated cascade synthetic transformations in the near future.
