MOBINIKHALEDI, Akbar; FOROUGHIFAR, Naser; MOHAMMADLU, Parvin  and  KALHOR, Mehdi. Synthesis of some benzimidazole-substituted benzotriazoles. S.Afr.j.chem. (Online) [online]. 2008, vol.61, pp.141-143. ISSN 1996-840X.

2-Alkylsubstituted benzimidazoles ( 3A-H: ) were prepared from the acid-catalyzed reaction of 4-methyl-1,2-phenylenediamine with corresponding carboxylic acids. Addition of these benzimidazoles to N-chloromethylbenzotriazole in the presence of sodium amide under reflux conditions gave the novel benzimidazole-substituted benzotriazoles ( 5A-F: ). IR and ¹H NMR spectroscopy and elemental analysis were used for the identification of these compounds.

Keywords : Phenylenediamine; benzimidazole; benzotriazole.
