Methanol → 2-Methoxy-1-formylpiperidine

Participants

Reaction Steps

In the cell and device as described in Example 2 a mixture of 480 g of 1-formylpiperidine, 1,360 g of methanol and 6.80 g of tetramethylammonium tetrafluoroborate was electrolyzed for 34 hours and 15 minutes at 1 A (corresponding to 240 Ahr), 98 volts and 25° C. By distillative work up, 577 g of 1-formyl-2-methoxypiperidine could be isolated from the clear electrolyte, corresponding to a current efficiency of 90.2% of the theory.
