YieldReaction ConditionsOperation in experiment
86% 1,4-bis(4-carboxyphenyl)benzene (420 mg, 1.21 mmol) was suspended in THF (65 mL). A solution of KOH (6.17 g, 110 mmol) dissolved in MeOH (20 mL) was then added, and the reaction mixture was stirred at 60 C. for 24 h. The suspension was cooled to room temperature and the resulting precipitate was collected by centrifugation. The solution was washed with dry THF (20 mL) and recollected by centrifugation. The solid was suspended in THF (20 mL) and trifluoroacetic acid (3 mL) was slowly added and stirred for 1.5 h at room temperature. H2O (15 mL) was then added, and the white solid was isolated by centrifugation, and subsequently washed with THF and Et2O, and dried in vacuo to obtain 1,4-bis(4-carboxyphenyl)benzene (331.9 mg, 1.04 mmol, 86% yield) as a pale-white solid. 1H NMR (500 MHz, DMSO-d6) delta 13.00 (br s, 2H), 8.05 (d, 4H, 3JHH=8.3 Hz), 7.89 (s, 4H), 7.88 (d, 4H, 3JHH=8.3 Hz).
