Iron catalyzed arene c-h hydroxylation

WebA new iron-catalyzed reaction for the coupling of perfluoroalkyl iodides (R F I) with aromatic substrates is described. The perfluoroalkylated arene products are obtained in good to excellent yields in the presence of a [ (bpy)Fe ( II )] catalyst (10%) electrochemically regenerated or generated from [ (bpy)Fe ( III )] at room temperature.
