It was found that bromination of 2-allylthiobenzimidazoles in organic solvents forms products of addition of bromine to the olefin bond - 2,3-dibromopropylthiobenzimidazoles, whch spontaneously or on heating cyclize into 3-bromobenzimidazo-1,3-thiazines or cyclodehydrobromination products - 2H- or 4H-benzimidazo-1,3-thiazines.

Heterocyclizations of 2-allylthiobenzimidazoles under the action of bromine yield 3-bromo-3,4-dihydro-2H-benzimidazo[2,1-b][1,3]thiazine and 2H- or 4H-benzimidazo[2,1-b][1,3]thiazines via intermediate formation of 2-(2,3-dibrompropylthio)benzimidazoles. P
