实验步骤: A dried 125 mL fluoropolymer (FEP) vessel was flowed with N2 gas and charged with 48.0 g (2.40 mmol) of liquid anhydrous hydrogen fluoride which was cooled at −20° C. The vessel was set with a condenser (made of fluoropolymer) and a thermometer, and cooled in a bath of −20° C. A coolant (−15° C.) was flowed through the condenser. Into the vessel, 8.6 g (0.11 mol) of KF.HF was added. While the mixture was warmed to +15° C., 22.1 g (96.2 mmol) (purity 96 wt % and the other was phenylsulfur trifluoride) of phenylsulfur chlorotetrafluoride was added to the mixture over 1 hour through a syringe. The temperature of the reaction mixture was 3.4° C. and 13.6° C. at the starting point and completing point of the addition, respectively. After the addition, the reaction mixture was stirred at 15° C. for 18 h. After that, the reaction mixture was warmed to 25° C. and hydrogen fluoride was removed under atmospheric pressure. The residue was neutralized with about 15% aqueous KOH and extracted with dichloromethane. The organic layer was separated, dried over anhydrous magnesium sulfate, and filtered. The filtrate was concentrated by distilling the solvent at 70° C. under atmospheric pressure. The resulting residue was distilled under reduced pressure to give 14.4 g (yield 73%) of phenylsulfur pentafluoride (boiling point 57.5° C./35 mmHg). The purity of the product was determined to be 100% by GC analysis. The product was identified by spectral comparison with an authentic reference sample.
