    • note
    • Aryl radicals are very reactive species able to react rapidly with most organic molecules, including the solvent itself and other aromatic species. However, the reaction with the surface is favored because the generation of the radical occurs at a very short distance from the electrode surface (see ref 7b).

    • 15f To explain this observation, a similar mechanism was proposed (see Scheme 1) in which the diazonium salt is reduced by thermal electron transfer at the open circuit potential of the substrate material in solution. Since the potential necessary to reduce a diazonium salt is quite positive (around 0 V/SCE), such nonstimulated reduction is unlikely to occur with noble metals such as Pt.

    • The characteristic Br3d signal at 71 eV cannot be unambiguously ascribed since the Pt4f signal is located in the same binding energy range (70.7 eV).

    • The reduction of nitro compounds may lead to different groups (amine, hydroxylamine, ...) depending on the quantity of residual water and reaction time.
