of benzo- and dibenzo-(hetero)aromatic compounds without formal leaving groups is achieved efficiently in organic solvent: water mixtures under photostimulation. The methodology is compared to previously reported trifluoromethylation strategies of these nuclei in terms of product yields and regioselectivity. The global reaction is a radical homolytic aromaticsubstitution process, where the perfluoroalkyl-substituted
