Disulfur difluoride


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:

Synthesis

can fluorinate sulfur in a strictly dry container, and the reaction produces FS-SF:
S=SF2 can be synthesized with the reaction of potassium fluorosulfite and disulfur dichloride:
