Bis trifluoromethyl sulfur Difluoride

At 25°C. bis(trifluoromethyl)sulfur difluoride is a colorless gas which condenses, on cooling, to a colorless liquid. A boiling point of

In the preparation of bis(trifluoromethyl)sulfur difluoride, explosions have occurred when chlorine mono- or tri-fluorides were treated with 2-3 mmol of the sulfide in absence of solvent. Because chlorine trifluoride is known to deprotonate solvents with formation of explosive carbene species, only fully halogenated solvents are suitable as diluents.

When treated with chlorine trifluoridc in CFC-12 at — 78 C, trifluoromethanesulfenyl chloride and bis(lrifluoromethyl) disulfide are transformed into trifluoromethylsulfur trifluoride (95%) and bis(trifluoromethyl)sulfur difluoride (90%). respectively.121... 

Oxidation of bis(trifluoromethyl) sulfide with commercially obtainable chlorine monofluoride in the absence of solvent yields bis(trifluoromethyl)sulfur difluoride in >90% yield.2,3 Pure bis-(trifluoromethyl)sulfur difluoride is resistant to hydrolysis and is stable in Pyrex glass at 25°C. for extended periods of time. Reaction of bis(trifluoromethyl)sulfur difluoride with anhydrous...
