Title

Synthesis of a Metal-Free Texaphyrin

Abstract

The synthesis of a metal-free form of texaphyrin, an aromatic porphyrin-like macrocycle, is described. Previously, texaphyrins could only be obtained reproducibly in the form of metal complexes. Using ferrocenium cation as the oxidizing agent and starting with a reduced porphyrinogen-like nonaromatic form of texaphyrin, we isolated, in good yield, the metal-free oxidized texaphyrin as its HPF6 salt. This product was characterized by X-ray diffraction analysis, UV−vis spectroscopy, and cyclic voltammetry.
