sulfuryl fluoride is one and is sulphur based

SO2CL2-sulfuryl chloride or sulphur oxy chloride

Sulfuryl flouride has negligible effect on the ozone layer (in current concentrations), however...

CFCs are heavier than air and so is sulfuryl flouride. We see these gases at the elevation of the ozone layer. We've measured their concentration there. Diffusion does not care how heavy a molecule is. The molecular weight only controls how long it takes to get to an elevation, not whether or not it can get there.
