New zwitterionic compounds (9-12) and cyclic urea derivatives of benzimidazole as one (3), thione (4,6), selenone (5,7), tellurone (8) were prepared from enetetramines. The chemical structures of novel benzimidazole compounds were determined by FTIR,1 H NMR,13 C NMR spectroscopic methods and elemental analysis. © 2018, Turkish Chemical Society.
