Procedure
In 100 g of dichloromethane were dissolved 10 g (0.02 mole) of sodium 2-(1-adamantanecarbonyloxy)-1,1-difluoro-ethanesulfonate (purity 70%) and 80 g (0.02 mole) of a 4-tert-butylphenyldiphenylsulfonium bromide aqueous solution. The organic layer was separated, washed three times with 20 g of water, and concentrated. Diethyl ether was added to the residue for recrystallization, obtaining the target compound as white crystals. 11 g (yield 86%).
