Disulfur difluoride is a halide of sulfur, with the chemical formula S2F2.

Structure[edit]

Disulfur difluoride will undergo intramolecular rearrangement in the presence of alkali elements' fluorides, yielding the isomer S=SF2:[1]

Synthesis[edit]

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 potassium fluorosulfite and disulfur dichloride:

[3]

Reactions[edit]

  • Treated with water:
