الإجراء التجريبي

A 100 mL reactor was charged with 3.0 g (26% purity, 2.9 millimoles) of sodium 1,1-difluoro-2-(valeryloxy)ethanesulfonate obtained in Example 5-3 and 30 g of water, followed by adding dropwise an aqueous solution of triphenylsulfonium chloride [17.8 g (5.2 millimoles/1.8 equivalents) of triphenylsulfonium chloride and 16.2 g of water] at room temperature, followed by stirring at room temperature for 1.5 hours. Then, extraction was conducted by adding 30 mL of chloroform. The obtained organic layer was rinsed two times with water, followed by distilling a solvent off, thereby obtaining 0.96 g of the target triphenylsulfonium 1,1-difluoro-2-(valeryloxy)ethanesulfonate.
