Reaktionsschritte
To 0.1 mole of tetrabromoxylene, 0.17 mole of fumaronitrile, 0.66 mole of sodium iodide and 400 ml of anhydrous dimethylformamide were added and heated with stirring at 70 to 80° C. for 7 hours. The reaction solution was added to 800 g of ice water. To the deposited precipitate, about 15 g of sodium hydrogen sulfite was added and allowed to stand overnight. After filtration by suction and drying, while 2,3-dicyanonaphthalene was obtained by recrystallization from chloroform/ethanol in yield of 80%.
