oa South African Journal of Chemistry - Synthesis of some benzimidazole-substituted benzotriazoles : research article



2-Alkylsubstituted benzimidazoles () 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 (). IR and 1HNMR spectroscopy and elemental analysis were used for the identification of these compounds.
