Reaction Steps

18.32 g (30.66 mmol) of the obtained 9,10-di(2-biphenylyl)-2-bromo-9,10-dihydroanthracene-9,10-diol, 9.16 g (55.19 mmol) of potassium iodide, 17.55 g (165.56 mmol) of sodium phosphinate monohydrate, and 150 mL of glacial acetic acid were put into a three-neck flask, and the mixture was stirred for 5 hours at 120° C. Thereafter, 100 mL of 50% phosphinic acid was added to the mixture, followed by stirring for 1 hour at 120° C. After the reaction, the solution was washed with water, and the precipitate was filtered, recrystallized with chloroform and hexane, obtaining 11.4 g of 9,10-di(2-biphenylyl)-2-bromoanthracene as a light yellow solid in 66% yield.
