for the direct generation of acyl radicals fromα-diketones, and its selective conversion of nitrosoarenes to hydroxyamides or amides with AcOH or NaCl as an additive. The reaction was carried out under mild conditions in water with purple LEDs as the light source. A broad scope of substrates was demonstrated. Mechanistic experiments indicate that α-diketones cleave to give acyl radicals, with hydroxyamides

Hindered aromatic nitroso-compounds, prepared by oxidation of the corresponding amines with m-chloroperoxybenzoic acid, were converted into N-arylhydroxamic acids which could be obtained only in poor yield or not at all by the conventional reduction of nitro-compounds.
