Abstract

Abstract: The Te II /Te III ‐catalyzed dehydrogenative C−H phenothiazination of challenging phenols featuring electron‐withdrawing substituents under mild aerobic conditions and with high yields is described. These unexpected Te II /Te III radical catalytic properties were characterized by cyclic voltammetry, EPR spectroscopy, kinetic experiments, and DFT calculations.
