2-Phenylbenzimidazoles, 2-benzylbenzimidazoles, 2-phenyl-1H-naphtholimidazole, and 2-benzyl-1H-naphtholimidazole have been synthesized in excellent yields (77-98percent) by lead tetraacetate oxidation of suitable N-arylbenzimides, N-arylphenylacetamidines, N-α-naphthylbenzimidine, and N-α-naphthylphenylacetamidine respectively.The mechanism of nitrene insertation and intramolecular competitive nitrene insertation leading to these heterocycles has also been discussed.
