A synthesis of a 1,1'-bibenzimidazole (2; R = Me), through two successive heterocyclizations on 2,2'-azoaniline, is reported.Alternative routes to (2) by direct formation of the N-N bond from the appropriate N-substituted-benzimidazoles were unsuccessful.The dimer (2) shows great thermal and photochemical stability towards hydrogen abstraction and addition to olefins.Although the N-N bond can be easily cleaved by irradiation in ethanol, all attempts to detect the neutral radical benzimidazol-1-yl (1; R = Me) from (2) have been unsuccessful.Hydrogen abstraction by (1) is, however, observed with 1-iodobenzimidazole as the precursor.
