Procedure
20 g of β-dimethylamino-2-nitrostyrene, 1 g of CuCl and 300 ml of DMF were initially introduced into a 300 ml autoclave equipped with an aerating stirrer. The autoclave was heated to 50° C. and pressurized to 10 bar with air, and a pressure of 20 bar was then maintained using oxygen. After 2 h, the experiment was discontinued and 87.2% of o-nitrobenzaldehyde was obtained after working-up.
