β‐Fluorinated Porphyrins and Related Compounds: An Overview

Abstract

Abstract Apart from a few examples, β‐(poly)fluorinated and β‐(poly)perfluoroalkylated porphyrins were practically unknownuntil recently. In particular, β‐octafluoro‐ meso ‐tetraarylporphyrins remained elusive ligands owing to the lack of any convenient access. The aim of this microreview is to highlight recent progress in the synthesis and characterization of β‐fluoroporphyrins and β‐(perfluoroalkyl)porphyrins, two new classes of so‐called electron‐deficient porphyrins.
