A mild and rapid (diacetoxyiodo)benzene-mediated formal electrophilic alpha-azidation of 1,3-dicarbonyl compounds using commercially available Bu4NN3 as the azide source is reported. The reaction conditions employed are based on optimization studies conducted on the analogous halogenations with Et4NX (X = Cl, Br, 1).
