2-Aminobenzimidazoles (1) react with benzonitriles in the presence of anhydrous stannic chloride to give N-(benzimidazol-2-yl)arylamidines (2).Oxidative cyclisation of 2 with lead tetraacetate in dry benzene leads to 2-aryltriazolobenzimidaz

The position of the tautomeric equilibrium in unsubstituted 1,2,4-triazolobenzimidazole, as well as in its 2-methyl and 2-phenyl derivatives, was investigated by UV, IR, and PMR spectroscopy and by determination of the ionization constants.In all c

2-Aroylaminobenzimidazoles (2) have been converted into 1(2-benzimidazolyl)-5-aryl-1H-tetrazoles (4) by treatment with PCl5 followed by azidation with NaN3 in aqueous acetone solution.Pyrolysis of 4 in diphenylether yielded 2-aryl-1H-s-triazolobenzimidazoles (6).The product of benzylation of 6a has been characterised.A reasonable pathway for the formation of 6 from 4 has been suggested.
