-benzimidazole. Its electrophilicsubstitutionreactions (nitration, bromination, sulfonation, formylation, acylation) were studied. All the reactions occur in the 5-position of the thiophene ring. Only in the case of bromination in dichloroethane 5′,5(6)-dibromo-derivative was obtained. Data of the quantum-chemical calculations of the total positive charge on the carbonatoms of the protonated molecules
