A method for producing an arene with an aromatic CN bond ortho to an aromatic CO bond from a hydroxy arene comprising said aromatic CO bond is provided. This method comprising the steps a) ortho-oxygenating the hydroxy arene to produce an ortho-quinone, b) condensating the ortho-quinone with a nitrogen nucleophile to generate a compound of Formula (IVa) or (IVb), and c) allowing 1,5-hydrogen atom shift of the compound of Formula (IVa) or (IVb), thereby producing arenes with a CN bond ortho to a CO bond of Formula (Va) and (Vb), respectively:
