Reaktionsschritte

In the same manner as indicated in Example 6 there are electrolyzed 8.5 g of N-acetylpiperidine and 49.7 g of n-butanol in the presence of 0.3 g of tetramethylammonium tetrafluoroborate as conducting salt. After throughput of 2.5 Faraday per mol of N-acetylpiperidine the current is switched off. The calculated mean cell voltage is 91 volts. Work-up of the electrolysis solution gives 7.6 g of 1-acetyl-2-n-butoxypiperidine (boiling point 70° C./0.1 mbar; nD25 = 1.4656), which corresponds to a product yield of 56.8% and a current efficiency of 45.5%.
