ABSTRACT:
The novel compounds of the present invention are .beta.-octafluoro-meso-tetraarylporphyrins of formula (I) and their metallic complexes of formula (II): ##STR1## .beta.-octafluoro-meso-tetraaryl porphyrins are synthesized by reacting 3,4-difluoropyrrole with an aromatic aldehyde in the presence of boron trifluoride etherate, followed by oxidation. The difluoropyrrole used in this reaction is produced by reacting 3,3,4,4-tetrafluoropyrroline or its corresponding salt, 3,3,4,4-tetrafluoropyrrolidinium salt, with a base such as potassium tert-butoxide. The metalloporphyrins of the present invention are synthesized by deprontonating .beta.-octafluoro-meso-tetraarylporphyrin ligands and treating said ligands with metal ions.
