Participants

Reaction Steps

5,6,7,8-tetrafluoro-9,10-dihydroxy-2,3-dihydroanthracene-1,4-dione (1) (9.84 g, 31.3 mmol), 4,5,6,7-tetrafluoroisobenzofuran-1,3-dione (2) (5.75 g, 26.1 mmol), aluminum chloride (1.53 g, 11.5 mmol), and sodium chloride (10.0 g, 171 mmol) were thrown into a 200 mL autoclave made of SUS and heating was made at 280° C. for 1 hour. After the completion of the reaction, cooling was made down to room temperature, the reaction mixture was poured into dilute hydrochloric acid, and stirring was made at 100° C. for 1 hour. Subsequently, the mixture was filtered and the residue was washed with methanol, dichloromethane, toluene and ether in order. The obtained solid was vacuum-dried so as to obtain 11.5 g (yield of 85%) of 1,2,3,4,8,9,10,11-octafluoro-5,7,12,14-tetrahydroxypentacene-6,13-dione (3).
