Regiodivergent benzoylation of 2-methoxynaphthalene with benzoyl fluoride is presented using either Friedel–Crafts-type chemistry to give selectively the 1-isomer or cooperative NHC/photoredox catalysis to afford the 4-isomer exclusively. Along with arenes, regiodivergent aroylation also works for heteroarenes.
