Методика

The reduction of the diol was accomplished by taking 5.44 g of 9,10-bis(pentafluorophenyl)-9,10-dihydro-9,10-anthracenediol in 50 mL of acetic acid and refluxing it with 9 g of potassium iodide and 9 g of sodium hypophosphite for 4 hours. After cooling, white crystals were filtered off. The crude product was recrystallized using a 1:1 mixture of toluene and hexane to yield 2.00 g of 9,10-bis(pentafluorophenyl)anthracene with a melting point of 337-338° C.
