참여 물질

반응 단계

A solution of 168.12 g. (0.5 mole) of hexafluorobisphenol A in 1000 ml of acetone was reacted with 142.76 g. (1.2 moles) of propargyl bromide in the presence of 165.85 g. (1.2 moles) of potassium carbonate. The reaction mixture was stirred and heated under reflux for 72 hrs. After cooling it was filtered and the solvent (acetone) of the filtrate was evaporated on a Buchi Re 121 Rotavapor. The residue was dissolved in diethyl ether and washed first with a 5% NaOH solution and then three times with deionized water. Dipropargyl ether of hexafluorobisphenol A was obtained in 90% yield after evaporation of diethyl ether on a Rotavapor. The product was a light brown liquid with the following structure. ##STR11##
