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