Abstract

A novel strategy for site-selective benzylic C–H oxidation has been developed through mediated electrolysis. A bulky maleimide N-oxyl radical (MINO) generated by proton-coupled electrochemical oxidation of N-hydroxymaleimide (NHMI), serves as a hydrogen atom-transfer mediator. Good-to-excellent site selectivity was observed among different substrates, providing a practical approach for site-selective benzylic C–H oxidation. Additionally, the hydrogen-atom transfer mechanism for C–H electrochemical oxidation allows the oxidation to proceed at much lower anode potentials relative to direct electrolysis and with minimal reliance on the substrate's electronic properties.
