Visible light mediates efficiently the α-arylation of enol acetates by aryl diazonium salts under mild conditions using [Ru(bpy)3]Cl 2 as a photoredox catalyst. The broad scope of the reaction toward various diazonium salts and enol acetates was explored. The application of this reaction in the concise synthesis of 2-substituted indoles was demonstrated

Treatment of p-dinitrobenzene with active methylene compounds of rather weak acidity in the presence of t-BuOK in liq NH3 at -70'C leads to nucleophilic substitution of a nitro group, giving p-substituted nitrobenzenes in generally good yields.
