反応手順
A mixture of 80 g of diethyl malonate, 30 g of paraformaldehyde, 5 g of potassium acetate, 5 g of copper (II) acetate monohydrate and 200 ml of acetic acid was heated at 90° to 100° C. for 2 hours. Acetic acid was removed from the reaction mixture under reduced pressure, and the residue was evaporated under reduced pressure to obtain 44 g of bis(ethoxycarbonyl)ethylene.
