摘要：
An iminoiodane-enabled oxidative ring-opening of 2H-indazoles via C-N bond cleavage has been developedundermetal-free reaction conditions. This methodology afforded a new arrayof unsymmetrical ortho-N-acylsulfonamidatedazobenzenes with a wide functional group tolerance in good yields.The reaction potentially proceeds through the formation of a zwitterionicadduct, which is formed by the reaction between 2H-indazoles and iminoiodane.
