Abstract: Abstract: We report on a novel synthetic procedure to obtain β-aminoporphyrins with zinc(II) as the metal center by using the catalytic reduction of the parent Zn(II)β-nitroporphyrins with hydrogen in the presence of Pd/C using dimethylformamide as the solvent. This simple method allows the preparation of β-aminoporphyrins with substituents with diverse electronic properties: meso-tetraphenylporphyrin (TPP), meso-tetrakis(2,6-dichlorophenyl)porphyrin (TDCPP), and meso-tetrakis(2,3,4,5,6-pentafluorophenyl)porphyrin (TPFPP).
