Versuchsvorschrift

Acenaphthen-1-ol (88 mol) was dissolved in diethyl ether (150 mL) and cooled down to 0° C. Phosphorous tribromide (3.2 mL, 35 mmol) was then added slowly under nitrogen atmosphere. The reaction mixture was stirred for 30 minutes at room temperature and cooled to 0° C. The reaction mixture was partitioned with water and diethyl ether. The organic layer was dried over Na2SO4, filtered and the solvent evaporated in vacuo to yield the title compound as a yellow solid.
