We have successfully developed a novel electrolytic system using KBr as a mediator and solid-supported acids as a supporting electrolyte. In this system, solid-supported acids such as Amberlyst 15Dry (–SO3H) serve as not only a promoter of the dissociation of KBr but also a supporting electrolyte. Anodic oxidation of some benzyl alcohols using KBr and Amberlyst 15Dry (–SO3H) in the presence of 2,6-lutidine was successfully carried out to provide the corresponding benzaldehydes in good to excellent yields.
