Synthesis of a metal-free texaphyrin

Org Lett. 2001 Nov 29;3(24):3911-4. doi: 10.1021/ol016757s.

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 HPF(6) salt. This product was characterized by X-ray diffraction analysis, UV-vis spectroscopy, and cyclic voltammetry. [structure: see text]
