Toluene → Sodium 2-benzoyloxy-1,1,3,3,3-pentafluoropropanesulfonate

Participants

Reaction Steps

10.0 g of 1,1,3,3,3-pentafluoropropen-2-yl benzoate, which had been synthesized by a conventional technique, was dispersed in 72 g of water, after which 12.0 g of sodium hydrogen sulfite and 1.24 g of benzoyl peroxide were added. The reaction took place at 85° C. for 65 hours. The reaction solution was allowed to cool. Toluene was added, followed by separatory operation to separate a water layer. A saturated sodium chloride aqueous solution was added to the water layer whereupon white crystals settled out. The crystals were collected by filtration, washed with a small volume of saturated sodium chloride aqueous solution and then dried in vacuum, obtaining the target compound, sodium 1,1,3,3,3-pentafluoro-2-benzoyloxypropane-1-sulfonate. White crystals, 5.85 g (yield 43%).
