One-Pot Synthesis of a bis-Pocket Corrole through a 14-fold Bromination Reaction

A one-pot protocol, effecting 14-fold bromination with elemental bromine, has afforded copper β-octabromo-meso-tris(2,6-dibromo-3,5-dimethoxyphenyl)corrole, a new bis-pocket metallocorrole. The Cu complex underwent smooth demetalation under reductive conditions, affording the free corrole ligand, which in turn could be readily complexed to Mn^III and Au^III. A single-crystal X-ray structure was obtained for the Mn^III complex.
