Reported is the condensation between o-arylenediamines and nitroarenes enabled by a cooperative action of acid and base, providing a direct entry to 2-aryl-2H-benzotriazoles. The potential practicability of this methodology was demonstrated by 100 mmol-scale reactions and the synthesis of serotonin/dopamine receptor ligand and human growth hormone. (Figure presented.).

A palladium-catalyzed annulation of 2-(aryldiazenyl) aniline and dimethyl sulfoxide was developed to access N-aryl-1H-benzo[d]imidazol-1-amine in moderate to good yields. Activated by 1,4-diazabicyclo[2.2.2]octane bis(sulfur dioxide) adduct (DABSO), DMSO served as a “[dbnd]CH[sbnd]” fragment during this procedure. It represents a facile pathway leading to benzimidazoles.
