Versuchsvorschrift

Diphenylcyclopropenone (0.319 g, 1.55 mmol) and 3,4-dicyanopyridine (0.200 g, 1.55 mmol) were mixed in a dry, argon filled reaction flask. Chlorobenzene (2.5 mL) (oxygen free) was added, and the reaction was heated to 130° C. After 2 h the heating was stopped and the reaction was allowed to reach room temperature. Petroleum ether 40°-60° C. (2.5 mL) was added in order to obtain a complete precipitate of the product. The solvent was filtered off and the precipitate was washed with petroleum ether. The crude product was stirred with chloroform (30 mL) for 1 h. The dark chloroform solution was filtered off leaving the title product as a yellow precipitate.
