An efficient TEMPO-catalyzed oxidative CâC bond formation with two Csp3âH bonds using molecular oxygen as the oxidant has been developed. The novel transformation provides a new strategy for the TEMPOâO2 catalysis to construct CâC bonds. The advantages of this method include: (1) relatively mild and neutral conditions; (2) simplicity and safety of operation; (3) a stoichiometric amount of dangerous oxidants, any transition metals, additives, even solvent, is not required.
