실험 절차

In 150 g of dichloromethane were dissolved 20 g (0.052 mole) of sodium 2-(pivaloyloxy)-1,1-difluoroethanesulfonate (purity 70%) and 217 g (0.052 mole) of 4-tert-butylphenyl-diphenylsulfonium bromide in water. The organic layer was separated and washed three times with 50 g of water. The organic layer was concentrated and diethyl ether was added to the residue for recrystallization. The target compound was obtained as white crystals, 26 g (yield 79%).
