実験手順
In the same manner as indicated in Example 5 there are electrolyzed 17.7 g of N-formylpyrrolidine and 57.2 g of methanol in the presence of 0.29 g of tetramethylammonium tetrafluoroborate as conducting salt. In this case, however, the current is switched off after the throughput of already 2.0 Faraday per mol of N-formylpyrrolidine. The calculated mean cell voltage is 28.8 volts. Work-up of the electrolysis solution gives 20.0 g of 1-formyl-2-methoxypyrrolidine (boiling point 39°-40° C./0.1 mbar; nD25 =1.4700), which corresponds to a product yield of 86.6% and a current efficiency of 86.6%.
