2.4 Organocatalyst/Photocatalyst Dual Catalysis

Abstract

Recent advances in dual-catalytic methods combining organocatalysis with (visible-light) photocatalysis are detailed within this chapter. It summarizes general aspects together with selected state-of-the-art procedures, highlighting both pioneering examples and current developments.The merger of organocatalysis with photocatalysis has proven to be enormously powerful, not only because it provides a synthetic platform to readily access radical intermediates within an organocatalytic manifold and its potential to alter the reactivity of typical organocatalytic intermediates, but also due to the new opportunities in asymmetric synthesis. The synergistic dual combination with organocatalysis enables photocatalytic reactions to be conducted in an enantioselective fashion and thereby has had a profound influence on several fields of current chemical research, including radical chemistry.
