Sulfuric Acid → HCID 66783297, compound

Participants

Reaction Steps

To a 100 ml three-necked flask were added 1.00 g (2.83=mol) of 4-bromo-5-iodophthalic anhydride synthesized in the above, 1.29 g (3.11 mmol) of 1,2-didodecylbenzene, and 4 ml of tetrachloroethane. Thereto was added 0.82 g (6.15 mmol) of aluminum chloride, followed by 3 hours of stirring at room temperature. Ice was added portionwise to the resulting reaction mixture to quench the reaction, followed by extraction with toluene. The extract was concentrated under reduced pressure to obtain 2.5 g of a viscous matter. To the viscous matter was added 8 ml of sulfuric acid, followed by 2 hours of stirring at 80° C. The resulting reaction mixture was cooled to room temperature and ice was added. The mixture was extracted with toluene and the organic phase was dried over sodium sulfate. Then, the phase was filtrated and concentrated under reduced pressure to obtain 678 mg of 2-bromo-3-iodo-6,7-didodecylanthraquinone (yield 35%).
