A range of nitro compounds are smoothly reduced to their corresponding oximes under the synergistic effects of visiblelight irradiation, the Ru(bpy)3Cl2 photocatalyst, Hünig’s base, Mg(ClO4)2 activation, and MeCN solvent. This remarkably mild and environmentally benign protocol, when orchestrated with classical Beckmann rearrangement, enables such high-value industrial feedstock as caprolactam to
