A Convenient Electrochemical One‐Pot Direct Synthesis of 2H ‐Indazoles via N–N Coupling

This article describes an environmentally friendly synthesis of a 2H‐indazole derivative via N–N bond coupling using the interaction of 2‐azidobenzaldehyde and aniline in EtOH solvent. Constant Current electrosynthesis was performed in an undivided cell at ambient temperature with tetrabutylammonium hexafluorophosphate (Bu4NPF6) as a supporting electrolyte. The protocol's enticing qualities include clean synthesis, the use of electricity rather than chemical reagents, and atom economy.
