Versuchsvorschrift

A mixture of 41.4 g of 2-bromonaphthalene, 15.7 g of acetyl chloride and 28 g of aluminum chloride in 250 ml of nitrobenzene was stirred at 100° C. for 4 hours. The reaction mixture was poured onto ice water and the resulting solid filtered off, washed with water and distilled under reduced pressure. The distillate was recrystallized from hexane to yield 2-bromo-6-acetylnaphthalene.
