Reaction Steps
1,5-Diiodonaphthalene (8.4 g) was reacted with a mixture of 4.2 g CuCN and 40 ml DMF under reflux conditions overnight. The mixture was cooled and poured into 120 ml aqueous solution containing 12.6 g NaCN. The mixture was stirred for four hours and the filtered product was repeatedly washed with copious amounts of water and dried. The isolated crude product (3.6 g, 92% yield, m.pt., 258–260° C.) was recrystallized from toluene to yield 3.2 g of the product (81% yield, m.pt., 260–262° C.).
