Light-Assisted Cross-Dehydrogenative-Coupling Reactions
This chapter describes cross-dehydrogenative-coupling (CDC) reactions mediated by visible light. The main focus is on transformations of amines through the generation of reactive intermediates such as iminium ions, azomethine ylides, or α-amino radicals through photo-oxidations. The chapter sections are organized by different photocatalytic systems based on transition metal complexes, dyes and porphyrins, and semiconductors. Also discussed are factors that influence the activation of C–H bonds as well as reaction mechanisms involving electron transfer and sensitization.
