Examination of the acid-base properties of 5-hydroxybenzimidazoles has shown them to exist in nitromethane as the 5-hydroxy-tautomers.Substituents in the 2-position have a predominantly inductive effect on the basicity of the 3-nitrogen, rationalized as in other nitrogen heterocycles by the proximity of the substituents to the reaction center. Keywords: 5-hydroxybenzimidazole, its tautomers and derivatives; acid-base properties and the effect thereon of substituents; Taft and inductive constants.
