Abstract

Protonation of 2-(2-furyl)-, 2-(2-thienyl)-, and 2-arylpyrroles by sulfuric acid in ethanol was studied using electronic absorption Spectroscopy in the UV and visible regions. Pyrroles with heteroaromatic substituents are protonated at the α-positions of pyrrole and the heterocycle, resulting in the appearance of additional long-wave spectral bands. In the series of 2-arylpyrroles protonation capability is determined by the electronic effect of the phenyl ring substituents.
