Popis: | The NH acidities of a systematic series of 2-substituted benzimidazoles in acetonitrile were studied by potentiometric titration. It was found that the intramolecular interrelationships between the substituent in the 2 position and the acidity center have primarily inductive character and are expressed quantitatively by a dependence of the pKa = f(σm) type. |
