Procedure

To 2.4 g (11 mmol) of the resulting 4-methacryloyloxybenzoic chloride were added 4.9 g (10 mmol) of triphenylsulfonium 2-hydroxy-1,1,3,3,3-pentafluoropropane-1-sulfonate in Synthesis Example 1-11 and 20 g of methylene chloride, which was ice cooled. To the solution, a solution of 1.1 g (11 mmol) of triethylamine and 0.2 g (2 mmol) of N,N-dimethylaminopyridiene in 5 g of methylene chloride was added such that the temperature might not exceed 5° C., followed by stirring at room temperature for 3 hours. Thereafter, 11 g of 5% dilute hydrochloric acid was added. The organic layer was separated and washed with water whereupon methylene chloride was distilled off under vacuum. The residue was combined with 30 g of methyl isobutyl ketone and washed with dilute aqueous ammonia and then with water, whereupon the methyl isobutyl ketone was distilled off under vacuum. The residue was washed with diisopropyl ether and purified by silica gel chromatography. The target compound, triphenylsulfonium 1,1,3,3,3-pentafluoro-2-(4-methacryloyloxy-benzoyloxy)-propane-1-sulfonate was obtained as colorless oil (6.0 g, yield 88%). The compound has the following structure.
