Abstract
[GRAPHICS] A synthetic access to the first members of expanded corroles 1 and 2 is ach ieved through formation of two direct pyrrole-pyrrole links by an oxidative coupling reaction. Spectroscopic and structural analysis reveal that 1 and 2 are 22II aromatic macrocycles despite the nonplanar structure and proper ties resemble that of isocorroles rather than 22II sapphyrins.
