| Carbaporphyrins, porphyrin analogues in which one or more of the pyrrole subunits are replaced by carbocyclic rings, have been widely studied but few examples of dicarbaporphyrins have been reported. In this project, a novel dicarbaporphyrinoid system with two adjacent azulene subunits was synthesized by the ‘2+2' MacDonald methodology. This involved the condensation of dipyrrylmethanes with a diazulene dialdehyde, following oxidation, and protonation to afford the corresponding dihydrobromide salt. Proton NMR spectroscopy shows that the diazuliporphyrin system has borderline diatropic characteristics.
