2-Bromoanthraquinone → 2-Bromo-9,10-diphenyl-9,10-dihydroanthracene-9,10-diol

참여 물질

반응 단계

4.9 g (17 mmol) of 2-bromo-9,10-anthraquinone was put into a 300 mL three-neck flask. The atmosphere in the flask was substituted with nitrogen. 100 mL of tetrahydrofuran (THF) was added and dissolved well. After that, 18 mL (37 mmol) of phenyl lithium was dripped into the solution, and the mixture was stirred at room temperature for about 12 hours. After the reaction, the solution was washed with water. Then, the aqueous layer was extracted with ethyl acetate. The extracted solution and an organic layer were mixed to be dried with magnesium sulfate. After the drying, this mixture was suction-filtrated and the filtrate was concentrated, so that 2-bromo-9,10-diphenyl-9,10-dihydroanthracene-9,10-diol (about 7.6 g), which was an object, was obtained.
