Carbon Disulfide → Ethanedione, bis[4-(diethylamino)phenyl]-

Participants

Reaction Steps

To 11.6 g of anhydrous aluminum chloride, 60 ml of carbon disulfide was added, followed by dropwise addition of 30 g of N,N-diethylaniline under ice-cooling. Then, 10 g of oxalyl chloride was added dropwise thereto at 5° C. or lower, followed by the reaction for 1 hour with stirring. After the reaction, the reaction solution was poured into 100 ml of water and 200 ml of chloroform. The chloroform layer obtained by separation was washed with 2N hydrochloric acid, dried and concentrated. The residue was recrystallized from ethyl acetate to give yellow 1,2-bis(4-diethylaminophenyl)ethane-1,2-dione in an amount of 7.0 g.
