Hypervalent iodine mediated oxidation of 1,2-diaminobenzimidazole and its schiff bases: Efficient synthesis of 3-amino-1,2,4-benzotriazine and 2-aryl-1,2,4-triazolo[1,5-a]benzimidazoles

Hypervalent iodine mediated oxidation of 1,2-diaminobenzimidazole and its Schiff bases is described. The reaction produces 3-amino-1,2,4-benzotriazine and 2-aryl-1,2,4-triazolo[1,5-a]benzimidazoles efficiently. Georg Thieme Verlag Stuttgart.

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

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.
