YieldReaction ConditionsOperation in experiment
92% With sulfuric acid; In water; at 120℃; for 10h;Acidic aqueous solution; 4,4"-Dibromo-2,2"-methoxycarbonyl-[l,l ';4',l"]terphenyl 17 (0.50 g, 0.99 mmol) was added to H2SO4 (80%, 50.0 mL, prepared from 10.0 mL Of H2O and 40.0 mL of concentrated (99.99%) H2SO4) and the mixture was heated with stirring at 120C for 10 hours. The reaction mixture was poured into ice and the resulting mixture was filtered. The solid was washed with sodium hydrogen carbonate solution and water to provide 2,8-dibromo-indeno[l,2-b]fluorene-6,12-dione (18) (0.40 g, 92%). The crude product was used for the next step without any further purification, m.p: > 300C; MS(MALDI-TOF) m/z (M+): 440.7; and Elemental Analysis: C, 54.12; H, 1.72
