실험 절차
A mixture of 1-fluoro-2-(pentafluoro-λ6-sulfanyl)benzene (2.00 g, 9.00 mmol) and sulfuric acid (4 mL) was cooled in an ice bath. Nitric acid (4 mL) was added to the reaction mixture; after 5 minutes, the cooling bath was removed and stirring was continued at room temperature for 3 hours. The reaction mixture was then poured into ice (150 mL), and the resulting mixture was extracted with diethyl ether (2×75 mL). The combined organic layers were washed with saturated aqueous sodium chloride solution, dried over magnesium sulfate, filtered, and concentrated in vacuo to provide an oil. After addition of a seed crystal, the product was obtained as a solid. Yield: 1.99 g, 7.45 mmol, 83%. 1H NMR (400 MHz, CDCl3) δ 7.45 (br dd, J=10, 9 Hz, 1H), 8.46 (br ddd, J=9.1, 3, 3 Hz, 1H), 8.72 (dd, J=5.8, 2.7 Hz, 1H).
