The cyclocondensation of N-(prop-2-yn-1-yl)-o-phenylenediamines with phenyl isothiocyanate leads to the formation of 1-(prop-2-yn-1-yl)-1,3-dihydro-2H- benzimidazole-2-thiones irrespective of the substituent nature at the triple bond. Reactions of both mo

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.
