New Porphyrinoids:  Vanadyl(IV) Complexes of <i>meso</i>-Aryl-Substituted Corrphycene and 10-Oxocorrole Ligands

Abstract

Rare vanadyl corrphycene and vanadyl 10-oxocorrole complexes were obtained via an oxidative macrocyclization process by the treatment of 6,6'-di-p-tolyl-2,2'-bidipyrrin with VO(acac)2 in a hot dioxygen atmosphere. The geometric and electronic structures of the new porpyhrinoids were determined and showed the dependency of the spectral pattern from the aromaticity of the macrocyclic ligand.
