摘要：
Oxidation of anthranilamides, salicylamides and some beta -substituted amides with iodobenzene diacetate in methanolic potassium hydroxide led to a new and convenient synthesis of 2-benzimidazolones, 2-benzoxazolones and related compounds, respectively. The reaction probably occurs via initial Hofmann-type rearrangement followed by intramolecular cyclization of intermediate isocyanate.
