Synthesis and Strucural Characterization of New Benzimidazole Compounds Derived from Electron Rich Olefins Bearing 1,4-Bisbenzimidazole with CS2, PhNCS and Chalcogens

In this work, 1,4-bis(3-isopropylbenzimidazolidine-2-ylidene-1-yl)butane (1) and 1,4-bis(3,5(6)-dimethylbenzimidazolidine-2-ylidene-1-yl)butane (2) were reacted with oxygen, sulfur, selenium, tellurium, phenyl isothiocyanate and carbon disulfur. New zwitterionic compounds (9-12) and cyclic urea der...

Description
Summary:In this work, 1,4-bis(3-isopropylbenzimidazolidine-2-ylidene-1-yl)butane (1) and 1,4-bis(3,5(6)-dimethylbenzimidazolidine-2-ylidene-1-yl)butane (2) were reacted with oxygen, sulfur, selenium, tellurium, phenyl isothiocyanate and carbon disulfur. New zwitterionic compounds (9-12) and cyclic urea derivatives of benzimidazole as one (3), thione (4,6), selenone (5,7), tellurone (8) were synthesised from electron-rich olefins. The chemical structure of novel benzimidazole compounds were determined by 1H NMR, 13C NMR, FTIR spectroscopic techniques and elemental analysis.
