Versuchsvorschrift

To a solution of 37 grams (0.25 mole) of 5,6,7,8-tetrahydronaphthol in 150 ml of carbon tetrachloride was added dropwise with stirring a solution of 44 grams (0.25 mole) of bromine in 50 ml of carbon tetrachloride. When the addition was complete the mixture was stirred for 30 minutes at room temperature and then evaporated in vacuo to a residue which after two recrystallizations from hexane provided 13 grams (22.9 percent) of product, m.p. 83°-85°C.
