Sulfur chloride pentafluoride
Encyclopedia
Sulfur chloride pentafluoride is an inorganic compound
with the formula . It exists as a colorless gas at room temperature and is highly toxic. The compound has an octahedral geometry with symmetry. Sulfur chloride pentafluoride is the only commercially available reagent for addition to aliphatic compounds.
In contrast to the high reactivity and toxicity of , sulfur hexafluoride
, is inert and nontoxic despite having a very closely related chemical formula.
The reaction is of interest because many such molecules exhibit biological activity. The addition reaction is done in the presence of
and at low temperatures around -30 °C. is used similarly.
is also a precursor to O(SF5)2 (by oxidation) and F2NSF5 (from tetrafluorohydrazine
).
Inorganic compound
Inorganic compounds have traditionally been considered to be of inanimate, non-biological origin. In contrast, organic compounds have an explicit biological origin. However, over the past century, the classification of inorganic vs organic compounds has become less important to scientists,...

Sulfur hexafluoride
Sulfur hexafluoride is an inorganic, colorless, odorless, and non-flammable greenhouse gas. has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, it is poorly soluble in water but soluble in...

Reactivity
Sulfur chloride pentafluoride added under free-radical conditions across olefins. In this process, the chlorine group and the groups add to opposite ends of the double bond as shown in the following reaction with propene:- + → CH3CH(Cl)CH2SF5
