Abstract
Attempts to brominate 2-styryl and 1-methyl-2-styrylbenzimidazoles with Br- 2 in AcOH at RT in order to get the dibromostyrylbenzimidazoles, lead to br omination in the benzene ring of these benzimidazole derivatives. The ring brominated produces obtained have been assigned structures by X-Ray analyse s, in case of. N-methyl series, and alternate chemical synthesis, in case o f -NH series of compounds.
