Reaction Steps
A solution of 22.46 grams (79.5 mmol.) of bisphenol A and 75 ml. of pyridine in 200 ml. of methylene chloride was cooled to 0° C., and 50 grams (177 mmol.) of trifluoromethanesulfonic anhydride was added over 40 minutes at a rate to maintain the temperature of the reaction mixture below 10° C. The resulting clear yellow solution was allowed to warm to room temperature, stirred for 14 hours, diluted with methylene chloride and washed twice with 5% aqueous hydrochloric acid solution and three times with water. After drying over magnesium sulfate, the solvent was removed to yield bisphenol A bis(trifluoromethanesulfonate) as a white powder.
