AI Article Synopsis
- N-(2-Azidophenyl)azolium salts can be easily synthesized and react with copper(i) to create NHC complexes.
- The reaction leads to the efficient formation of benzimidazo-fused heterocycles under mild catalytic conditions.
- The proposed mechanism involves the elimination of dinitrogen and the cyclization of imido/nitrene with NHC.
Article Abstract
N-(2-Azidophenyl)azolium salts were easily prepared and reacted with copper(i) under conditions allowing the formation of NHC complexes. Under these conditions, the formation of benzimidazo-fused heterocycles occurred under catalytic, efficient and very mild conditions. This reaction is proposed to proceed via dinitrogen elimination and imido/nitrene-NHC cyclization.
