Synthesis and properties of a corrole with small and electron-withdrawing substitutents, 5,15-bis(trifluoromethyl)-10-penta-fluorophenylcorrole

Several methodologies for the synthesis of corroles that carry minimal-sized electron-withdrawing substituents at the meso-C atoms were investigated; of these the one based on dypyrromethane/aidehyde condensation was fruitful. The new corrole with one C6F5 and two CF3 groups, as well as its cobalt(III) complex, were fully characterized by spectroscopy and X-ray crystallography.
