An iminoiodane-enabled oxidative ring-opening of 2H-indazoles via C-N bond cleavage has been developed under metal-free reaction conditions. This methodology afforded a new array of unsymmetrical ortho-N-acylsulfonamidated azobenzenes with a wide functional group tolerance in good yields. The reaction potentially proceeds through the formation of a zwitterionic adduct, which is formed by the reaction between 2H-indazoles and iminoiodane.
