Biaryl Synthesis via Electrooxidative Transition-Metal-Catalyzed C–H Activation

Abstract The use of electricity as an inexpensive and waste-free oxidant opens up new opportunities for the development of sustainable C–H functionalization reactions. Herein we summarize recent advances in the synthesis of biaryls through electrooxidative processes involving transition-metal-catalyzed ortho-directed C–H activation. A particular focus is set on electrooxidative C–H/C–M couplings and dehydrogenative couplings. 1 Introduction 2 Electrooxidative C–H/C–M Couplings 3 Electrooxidative C–H/C–H Couplings 4 Conclusion and Outlook
