Manganese-Catalyzed C–H Activation
ACS Catalysis, 2016 Manganese is found in the active center of numerous enzymes that operate by an outer-sphere homolytic C–H cleavage. Thus, a plethora of bioinspired radical-based C–H functionalizations by manganese catalysis have been devised during the past decades. In contrast, organometallic C–H activation by means of manganese catalysis has emerged only recently as
