反応手順
In an atmosphere of argon, 60 g (550 mmole) of 1,4-benzoquinone, 100 g (240 mmole) of 1,2-bis(dibromomethyl)benzene and 235 g (1.6 mole) of sodium iodide were dissolved into 850 ml of dry dimethylformamide. After the exothermic reaction was completed, the reaction solution was heated to 70° C. and stirred for 8 hours. After the reaction was completed, the formed crystals were separated by filtration and washed with methanol and water and 23 g (the yield: 47%) of light yellow needle crystals of 1,4-anthraquinone were obtained.
