반응 단계
To 0.1 mol of tetrabromoxylene were added 0.17 mol of fumaronitrile, 0.66 mol of sodium iodide and 400 ml of anhydrous dimethylformamide, and the mixture was stirred under heating at 70° to 80° C. for 7 hours. The reaction mixture was added to 800 g of ice-water, and to the resultant precipitate was added about 15 g of sodium hydrogen sulfite and the mixture was left to stand overnight. Subsequently, the mixture was filtered and dried, followed by recrystallization from chloroform/ethanol, to give white 2,3-dicyanonaphthalene. The yield was 80%.
