| The efficient metal-free electrosynthesis of 2,4-dinitrophenyl iodide is here reported starting from 2,4-dinitrophenylhydrazine. Surprisingly this dinitrated arylhydrazine minimizes, under the applied experimental conditions, any anodic multilayered film formation. This sustainable iodide-mediated oxidative dehydrazination enables coupling reaction of electrogenerated iodine with aryl radicals from electron-deficient arylhydrazines employing electricity as the driving force and an inexpensive halogen source. A mechanistic proposal explaining the formation of aryl iodides is presented and discussed. |
