Demetalation of copper undecaarylcorroles: Molecular structures of a free-base undecaarylisocorrole and a gold undecaarylcorrole

Synopsis: Free-base undecaarylisocorroles are presented as a new class of sterically hindered macrocyclic ligands. One of these has been complexed, with concomitant aromatization, to yield a gold(III) undecaarylcorrole. Both a free-base undecaarylisocorrole and the gold undecaarylcorrole were fully structurally characterized. The significant solubility of the gold complex appears to be related to the absence of aurophilic/metallophilic interactions.77
