Nitration system NaNO2-TFA for regioselective nitration of the meso-positions of 5-phenyl-2,3,7,8,12,18-hexamethyl13,17-diethylporphine (1) was examined. The degree of nitration is easily controlled by the amount of NaNO2 used and by the reaction time. All compounds are characterized by MS, UV-Vis-, and 1H NMR-spectroscopy as well as massspectrometry. Protonation of transannular protons of some synthesized porphyrins is discussed.
