Reaction Steps

4,5,6,7-tetrafluoroisobenzofuran-1,3-dione (2) (5.75 g, 26.1 mmol), 5,6,7,8-tetrafluoro-9,10-dihydroxy-2,3-dihydroanthracen-1,4-dione (1) (9.84 g, 31.3 mmol), aluminum chloride (1.53 g, 11.5 mmol), and sodium chloride (10.0 g, 171 mmol) were added to a 200-mL SUS autoclave and heated for 1 hour at 280° C. After completion of the reaction, cooling to room temperature was carried out and the reaction mixture was then introduced into dilute hydrochloric acid and was stirred for 1 hour at 100° C. The mixture was then filtered and the residue was washed with methanol, dichloromethane, toluene, and ether in the sequence given. The resulting solid was vacuum dried to give 11.5 g (85% yield) 1,2,3,4,8,9,10,11-octafluoro-5,7,12,14-tetrahydroxypentacen-6,13-dione (3).
