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

${\rm {\ SCl_{2}+2KF{\xrightarrow {423K}}SF_{2}+2KCl}}$

${\rm {\ SCl_{2}+HgF_{2}{\xrightarrow {423K}}SF_{2}+HgCl_{2}}}$

The F-S-F bond angle is 98°, and the length of S-F bond is 159pm.
