Participants

Reaction Steps

10.1 g (15.2 mmol) of 1,1,1,3,3,3-hexafluoro-2,2-bis-[4-methyl-3-(2,2,2-trifluoro-1-hydroxy-1-trifluoromethyl-ethyl)-phenyl]-propane were dissolved in 50 ml of methylene chloride, and 3.4 g (33 mmol) of triethylamine were added at 0° C. 4.0 g (34.7 mmol) of methanesulfonyl chloride in 20 ml of methylene chloride were added dropwise at 0° to 5° C. The mixture was stirred for 24 hours at room temperature, separated off from the precipitated salt, washed with water, dried and evaporated down. The oily residue was recrystallized. 9.2 g of 1,1,1,3,3,3-hexafluoro-2,2-bis-[4-methyl-3-(2,2,2-trifluoro-1-methanesulfonyloxy-1-trifluoromethyl-ethyl)-phenyl]-propane were obtained (colorless crystals, m.p.: 135° C. [from toluene]).
