beta-fluorinated porphyrins and related compounds: An overview

Apart from a few examples, beta-(poly)fluorinated and beta-(poly)-perfluoroalkylated porphyrins were practically unknown until recently. In particular, beta-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 beta-fluoroporphyrins and beta-(perfluoroalkyl)porphyrins, two new classes of so-called electron-deficient porphyrins.
