Methanol → 1-Acetyl-2-methoxyhexahydroazepine

참여 물질

반응 단계

In the same manner as indicated in Example 6 there are electrolyzed 23.2 g of N-acetylhexahydroazepine and 57.7 g of methanol in the presence of 0.26 g of tetramethylammonium tetrafluoroborate as conducting salt. After throughput of 2.5 Faraday per mol of N-acetylhexahydroazepine the current is switched off. The calculated mean cell voltage is 40.8 volts. Work-up of the electrolysis solution gives 25.4 g of 1-acetyl-2-methoxyhexahydroazepine (boiling point 53° C./0.06 mbar; nD25 =1.4775), which corresponds to a product yield of 90.1% and a current efficiency of 71.5%.
