反応手順

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 and washed three times with 200 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, 164 g (yield 95%).
