Synthesis of p-Substituted Tetraphenylporphyrins and Corresponding Ferric Complexes

摘要：

Five kinds of p-substituted tetraphenylporphyrin compounds T(p-R)PPH2, R=NO2, Cl, CH3, OCH3, OH were synthesized by the condensation of p-substituted benzaldehyde with pyrrole by refluxing in mixed solvents (propionic acid, acetic acid and nitrobenzene) and the ferric complexes T(p-R)PPFe III Cl were synthesized in dimethylformamide (Scheme 1). Above free base porphyrins were obtained in 30%?50% yields, metalation yields were up to 90%, and total yields of ferric complexes were 27%?50%. Effects of reactive conditions, solvents and oxidants on yields of free base porphyrins were investigated and the relevant mechanism was discussed. Structures of above porphyrin complexes were characterized by UV-Vis, IR and FIR.
