Triphenylsulfonium chloride → Triphenylsulfonium 1,1,3,3,3-pentafluoro-2-benzoyloxypropane-1-sulfonate

Participants

Reaction Steps

To 50 g of dichloromethane were added an amount (corresponding to 0.011 mole) of the triphenylsulfonium chloride aqueous solution of Synthesis Example 1 and 3.6 g (0.01 mole) of sodium 2-benzoyloxy-1,1,3,3,3-pentafluoropropane-1-sulfonate synthesized in Synthesis Example 9, followed by stirring. The organic layer was separated and washed with 50 g of water three times. The organic layer was concentrated and 25 g of diethyl ether was added to the residue for crystallization. The crystals were filtered and dried, obtaining the target compound. White crystals, 4.5 g (yield 75%).
