Sulfur difluoride is an inorganic compound with the chemical formula SF2. It can be generated by the reaction of sulfur dichloride and potassium fluoride or mercury(II) fluoride at low pressures:

SCl2 \+ 2 KF → SF2 \+ 2 KCl
SCl2 \+ HgF2 → SF2 \+ HgCl2

The F−S−F bond angle is 98°, and the length of S−F bond is 159 pm.[1] The compound is highly unstable, dimerising to FSSF3. This unsymmetrical isomer of S2F4 is proposed to arise via insertion of SF2 into the S−F bond of a second molecule SF2:[2]

It can also be formed from oxygen difluoride and hydrogen sulfide:[citation needed]

OF2 \+ H2S → SF2 \+ H2O
