Ini ally op mizing the reac on condi ons in batch was achieved using the Electrasyn reactor. Screening common electrode and electrolyte combina ons found in the literature for Shono oxida on chemistry, we quickly se led on using graphite as both the anode and cathode to simplify the setup and using tetraethylammonium tetrafluoroborate (TEA-BF4) as the electrolyte salt which gave the lowest level of reac on impuri es of the electrolytes screened. Methanol was used both as the reac on solvent and as the nucleophile.
