Disulfur difluoride is a halide of sulfur, with the chemical formula S2F2.
Structure[]
Disulfur difluoride will undergo intramolecular rearrangement in the presence of alkali elements' fluorides, yielding the isomer S=SF2:[1]
Synthesis[]
Silver(II) fluoride can fluorinate sulfur in a strictly dry container, and the reaction produces FS-SF:[2]
S=SF2 can be synthesized with the reaction of and disulfur dichloride:
Reactions[]
- Decomposing to sulfur tetrafluoride and sulfur when heated:
- Treated with water:
- Reacting with sulfuric acid:
- Reacting with sodium hydroxide:
- Reacting with oxygen at high pressure, using nitrogen dioxide as the catalyst:
- Condensing with sulfur difluoride at low temperatures to yield 1,3-Difluoro-trisulfane-1,1-difluoride.
- SSF2 + SF2 → FSSSF3[7]
