A sulfone. It consists of a sulfonyl group bonded with two organic substituents.

In organosulfur chemistry, a sulfonyl group is either a functional group found primarily in sulfones, or a substituent obtained from a sulfonic acid by the removal of the hydroxyl group, similarly to acyl groups.[1]Template:Rp

Group

Sulfonyl groups can be written as having the general formula Template:Chem2, where there are two double bonds between the sulfur and oxygen.[1]Template:Rp[2]

Sulfonyl groups can be reduced to the sulfide with diisobutylaluminium hydride (DIBALH). Lithium aluminium hydride (Template:Chem2) reduces some but not all sulfones to sulfides.[1]Template:Rp

In inorganic chemistry, when the group Template:Chem2 is not connected to any carbon atoms, it is referred to as sulfuryl.[3]

Examples of sulfonyl group substituents

The names of sulfonyl groups typically end in -syl, such as:[1]Template:Rp
