Procedure

Into a 500 mL flask as described in Example II was charged 48 g (1.50 mole) of sulfur, 5 g (0.086 mole) anh. KF and 200 mL of dimethyl sulfoxide. Hexafluoropropene (133 g, 0.89 mole) was reacted over a 6 hour period at 55° C. to give 104 g (0.275 mole) of crude hexafluorothioacetone dimer for a 62% conversion and yield.
