Β-Fluorinated Porphyrins and Related Compounds : An Overview

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.
