Benzylic C–H bond functionalization through photo-mediated mesyloxy radical formation

Year: 2025

Type: article

Abstract: A photo-mediated method for selective benzylic C–H oxygenation uses in situ (methylsulfonyloxy)pyridinium salts as mesyloxy radical precursors. Mechanistic studies support an HAT-ORPC pathway via fluorescence quenching and cyclic voltammetry.
