Reaktionsschritte
In the same manner as indicated in Example 6 there are electrolyzed 21.6 g of N-acetylpiperidine and 54.4 g of methanol in the presence of 0.56 g of tetra-n-propylammonium hexafluorophosphate as conducting salt. After throughput of 2.0 Faraday per mol of N-acetylpiperidine the current is switched off. The calculated mean cell voltage is 28.7 volts. Work-up of the electrolysis solution by molecular distillation gives 21.5 g of 1-acetyl-2-methoxypiperidine, which corresponds to a product yield of 80.5% and a current efficiency of 80.5%.
