Procedure
11.5 g (0.205 mol) of potassium hydroxide are added to a solution of 42.6 g (0.1 mol) of 2,2-bis-(4-hydroxy-3-nitrophenyl) -hexafluoropropane and 39.1 g (0.205 mol) of p-toluenesulfonyl chloride in 300 ml of methylene chloride. The reaction mixture is then stirred at room temperature for five hours, in the course of which it turns an orange-yellow color. After precipitated potassium chloride (16 g) has been removed, the filtrate is dried over MgSO4. Removing the solvent and recrystallizing from toluene gives 43 g of 2,2-bis-(3-nitro-4-tosyloxyphenyl)-hexafluoropropane. Yield 58%; m.p. 206-208° C.
