2,5-Dimethoxy-2,5-dihydrofuran was prepared by the oxidation of furan and by the reduction of methanol solvent using a thin layer flow cell geometry with anode and cathode directly facing each other and without intentionally added electrolyte. Controlling factors for this kind of self-supported paired electrosynthesis, such as the electrode material, the current density, and the flow rate were optimized. The maximum chemical yield of 98% of pure product without work-up could be obtained with a combination of a glassy carbon anode and a platinum cathode in a single pass of furan solution.
