A 6,11,16-Triarylbiphenylcorrole with an adj-CCNN Core: Stabilization of an Organocopper(III) Complex

An adj‐dicarbacorrole with CCNN in the core is achieved by replacing the bipyrrole moiety by a simple polycyclic aromatic hydrocarbon, such as biphenyl unit. Spectroscopic studies and structural analyzes confirm the absence of macrocyclic aromatization, thus leading to overall nonaromatic character. The trianionic core is effectively utilized to stabilize a copper(III) ion to form an organocopper complex. A biphenyl unit is incorporated in the corrole macrocyclic framework to form an adj‐dicarbaporphyrinoid with a CCNN core. Upon macrocyclic aromatization, the aromatic biphenyl unit and π‐delocalized dipyrromethene unit are linked together to generate overall nonaromatic character. The trianionic core is suitable to stabilize higher‐oxidation‐state metal complexes, such as an organocopper(III) complex.
