Abstract

5,15-Bis(veratryl)porphyrin (1), 5,10,15-tris(veratryl)porphyrin (2), and 5,10,15,20-tetrakis(veratryl)porphyrin (3), C36H30N4O4, C44H38N4O6, and C52H46N4O8 were synthesized by an acid-catalyzed, one-pot reaction of meso-dipyrromethane, 3,4-di-OCH3-benzaldehyde (veratraldehyde), and trifluoroacetic acid (TFA). These three different products were obtained as a result of scrambling reactions. The molecular structures have been characterized by elemental analysis, ESI mass spectra, 1D and 2D NMR techniques (1H and 13C), and UV-visible spectroscopy. Copyright © Taylor & Francis Group, LLC.
