Triply Linked Corrole Dimers

The oxidation of 10–10′ singly linked corrole dimers with DDQ at low concentration in CHCl 3 afforded meso–meso, β–β, β–β triply linked 2 H ‐corrole dimers (with two inner NH groups in each corrole unit), which exhibited characteristic 1 H NMR and absorption spectra attributable to their nonaromatic electronic networks. These 2 H ‐corrole dimers were reduced with NaBH 4 to aromatic 3 H ‐corrole dimers, which were unstable and easily oxidized back to the 2 H ‐corrole dimers upon exposure to air. Bis(zinc(II)) complexes of the 2 H ‐corrole dimers were synthesized and characterized as rare examples of nonaromatic zinc(II) corrole complexes.
