Continuous Flow Organocatalytic C–H Functionalization and Cross-Dehydrogenative Coupling Reactions: Visible Light Organophotocatalysis for Multicomponent Reactions and C–C, C–P Bond Formations

A continuous flow procedure for the efficient metal-free, visible light photoredox-catalyzed α-functionalization of tertiary amines has been developed. Rose Bengal has been identified as an effective organic photocatalyst for continuous flow C–C and C–P bond formations as well as multicomponent reactions.
