실험 절차

About 6 g of the diphenyl-4-hydroxyphenylsulfonium trifluoromethanesulfonate salt manufactured in the synthesis example 3 and about 4.84 g of a benzoic acid-2,2-difluoro-2-sulfo-ethyl ester sodium salt were dissolved in about 100 ml of an MC and about 100 ml of water, and a synthesis reaction (see Equation 9 below) was performed while strongly stirring for about three hours. In this instance, a process of the synthesis reaction was observed by 19F NMR using a small amount of an extracted organic phase. The organic phase was extracted when the synthesis reaction was terminated, and washed using the MC of a soluble solvent and hexane of a sparingly soluble solvent. Next, the solvents were removed, and drying under a reduced pressure was performed to obtain about 4.3 g (a yield: about 56.4%) of a benzoic acid-2,2-difluoro-2-sulfo-ethyl ester diphenyl-4-hydroxyphenylsulfonium salt, and a structure of the benzoic acid-2,2-difluoro-2-sulfo-ethyl ester diphenyl-4-hydroxyphenylsulfonium salt was observed by 1H-NMR (see FIG. 8):
