Versuchsvorschrift

In 700 g of dichloromethane and 400 g of water were dissolved 159 g (0.37 mole) of sodium 2-(pivaloyloxy)-1,1-difluoroethanesulfonate (purity 63%) and 132 g (0.34 mole) of triphenylsulfonium iodide. The organic layer was separated, washed three times with 200 g of water, and concentrated. Diethyl ether was added to the residue for recrystallization, obtaining the target compound as white crystals. 164 g (yield 95%).
