Reaction Conditions

Reaction Steps

After 3.33 g (10 mmol) of 9-bromo-10-phenylanthracene was dissolved in 80 mL of tetrahydrofuran (abbreviation: THF) and cooled to −78° C., 7.5 mL (12.0 mmol) of n-BuLi (1.6 mol/L) was dropped through a dropping funnel into the reaction solution, and the mixture was stirred for one hour. Subsequently, a solution of 5 g (20.0 mmol) of iodine dissolved in 20 mL of THF was dropped, and the solution was further stirred at −78° C. for two hours. After the reaction, a sodium thiosulfate aqueous solution was added to stop the reaction. An organic layer was washed with a sodium thiosulfate aqueous solution and saturated saline and dried with magnesium sulfate. After the solution was filtered naturally, the filtrate was concentrated and recrystallized with ethanol; thus, 3.1 g of a light-yellow solid of 9-iodo-10-phenylanthracene as a target matter was obtained with a yield of 83%.
