Crossover Linstead macrocyclization of cycloheptatrienylmaleonitrile and (dimethylamino)-maleonitrile gave access to an unsymmetrical (A3B) porphyrazine bearing six peripheral amino substituents and a fused cycloheptatrienyl ring. Subsequent hydride abstraction gave a tropylium-fused aminoporphyrazine, which contains both strongly electron-donating and withdrawing groups and thus can be labelled as a 'push-pull' macrocycle. Detailed structural studies of this novel porphyrazine are described.
