Procedure

Into a 500 mL flask as described in Example II was charged 32 g (1.0 mole) sulfur, 22 g (0.38 mole) of anhydrous KF and 200 mL tetramethylene sulfone. The mixture was heated to 45°-65° C. and 60 g (0.40 mole) of hexafluoropropene was fed to the reaction mixture over a 3 hour period. There was recovered 60 g (0.40 mole) of unreacted hexafluoropropene in the dry-ice-acetone trap indicating that no reaction with sulfur had taken place. No hexafluorothioacetone dimer was isolated from the reaction mixture.
