9-Phenylanthracene → 9-Bromo-10-phenyl-anthracene

Participants

Reaction Steps

After 6.0 g (23.7 mmol) of 9-phenylanthracene was dissolved in 80 mL of carbon tetrachloride, a solution of 3.80 g (21.1 mmol) of bromine dissolved in 10 mL of carbon tetrachloride was dropped through a dropping funnel into the reaction solution. After the dropping, the solution was stirred at room temperature for one hour After the reaction, a sodium thiosulfate aqueous solution was added to stop the reaction. An organic layer was washed with a sodium hydroxide (NaOH) aqueous solution and saturated saline and dried with magnesium sulfate. After the solution was filtered naturally, the filtrate was concentrated, dissolved in toluene, and filtered through Florisil, Celite, and alumina. When the filtrate was concentrated and recrystallized with dichloromethane and hexane, 7.0 g of a light-yellow solid of 10-bromo-9-phenylanthracene, which is a target matter, was obtained with a yield of 89%.
