Two-step access to bis- meso -perfluoroalkyl-corroles towards meso -perfluoroacyl-ABC-corroles.

A solventless and acid-catalyzed condensation of meso -perfluoroalkyl-dipyrromethanes with selected benzaldehydes was used to prepare ten different bilanes that were isolated before their oxidation into trans -A 2 B-corroles bearing two meso -perfluoroalkyl groups. Macrocycles bearing long chains (C 3 F 7 or C 7 F 15 ) are key precursors to afford ABC-corroles having a meso -acyl substituent when subjected to a mild and basic hydrolysis affecting one of the alkyl substituents.
