ARTICLESynthesis of 2-Substituted Benzimidazoles and 1,5-Disubstituted Benzodiazepines on Alumina and Zirconia Catalysts
Graphical abstract
The presence of amount of surface acid sites, morphology of the catalyst, and presence of manganese oxide on the surface of the catalyst plays a synergistic role in the synthesis of benzimidazoles and benzodiazepines.

Green synthesis of benzimidazole derivatives by using zinc boron nitride catalyst and their application from DFT (B3LYP) study
2022, HeliyonCitation Excerpt :The first protocol involves a coupling of 1,2-phenylene-diamines with carboxylic acids, whereas the second protocol involves condensation of 1,2-phenylenediamine with aldehydes followed by oxidative cyclodehydrogenation [25, 26]. Benzimidazole moiety can be constructed through reactions involving the use of several types of catalysts such as ammonium chloride [27], alumina [28], sodium metabisulphite [29], lanthanum chloride [30], indium triflate [31], sodium hexafluroaluminate [32], nickel acetate [33], iodine [34], and sodium dodecyl sulfate [35]. At the same time, some biologically active quinoline molecules are synthesized using boron modified sulphonic acid catalyst [36, 37, 38].
Selective production of imines and benzimidazoles by cooperative bismuth(III)/transition metal ion catalysis
2022, Journal of CatalysisCitation Excerpt :The utilization of high performance manganese- and nickel-based catalysts, which are known to bear great promises as catalysts in green chemical approaches [42], is still largely underexplored. To the best of our knowledge, only some aspects of manganese promoted cyclocondensations have been investigated so far [43]. In order to successfully address these challenges, cooperative catalysis with the aid of Lewis acids and (3d) transition metal ions with variable charge could provide an interesting new perspective [44–47].
