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

Participants

Reaction Steps

6.0 g (23.7 mmol) of 9-phenylanthracene was dissolved into 80 mL of carbon tetrachloride, and a solution in which 3.80 g (21.1 mmol) of bromine was dissolved in 10 mL of carbon tetrachloride was dropped into the reaction solution using a dropping funnel. After dropping, the solution was stirred for 1 hour at a room temperature. After the reaction, an aqueous sodium thiosulfate solution was added to stop the reaction. An organic layer was washed with an aqueous sodium hydroxide (NaOH) solution and a saturated sodium chloride solution and dried with magnesium sulfate. The mixture was naturally filtered, and a compound obtained by concentrating the filtrate was dissolved into toluene and filtered through florisil, Celite®, and alumina. The filtrate was concentrated and recrystallized with dichloromethane and hexane, thereby obtaining 7.0 g of objective 10-bromo-9-phenylanthracene as a light-yellow solid with a yield of 89%.
