1-Amino-2-R-benzimidazoles are oxidized by lead tetraacetate to give, depending on the substituent in the 2-position, either to 1,1'-azobenzimidazoles (R=H, CH3, C6H5, Cl, N(CH3)2) or 3-R-benzo-1,2,4-triazines (R=NH2, NHCH3, NHC6H5, OH).The factors affecting the course of the reaction are discussed.The physicochemical properties of the 1,1'-azobenzimidazoles obtained have been examined.
