実験手順
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 an aqueous solution of 4-tert-butylphenyldiphenylsulfonium bromide. The organic layer was separated, washed three times with 50 g of water, and concentrated. Diethyl ether was added to the residue for recrystallization, obtaining the target compound as white crystals. 26 g (yield 79%).
