Synthesis of novel bis- and poly(hydrazinylthiazole) linked to benzofuran or benzothiazole as new hybrid molecules

Abstract

A novel series of bis- and poly(thiazoles) substituted with benzofuran and benzothiazole moieties were prepared in good yields by the reaction of the appropriate bis(α-bromoketones) with the corresponding bis- and poly(hydrazinecarbothioamide) in refluxing EtOH in the presence of TEA. The structures of the new compounds were confirmed based on elemental analyses as well as spectral data.
