A sulfonyl group can refer either to a functional group found primarily in sulfones or to a substituent obtained from a sulfonic acid by the removal of the hydroxyl group similarly to acyl groups. Sulfonyl groups can be written as having the general formula R-S(=O)2-R', where there are two double bonds between the sulfur and oxygen.
Sulfonyl groups can be reduced to the hydrocarbon with lithium aluminium hydride (LiAlH4).
In inorganic chemistry, when the group -S(=O)2- is not connected to any carbon atoms, it is referred to as sulfuryl.
Examples of sulfonyl group substituents
The names of sulfonyl groups typically end in -syl, such as:
| Group name | Full name | Pseudoelement symbol | Example |
|---|---|---|---|
| Tosyl | p-toluenesulfonyl | Ts | Tosyl chloride (p-toluenesulfonyl chloride) CH3C6H4SO2Cl |
| Brosyl | p-bromobenzenesulfonyl | Bs | |
| Nosyl | 2- or 4-nitrobenzenesulfonyl | Ns | |
| Mesyl | methanesulfonyl | Ms | Mesyl chloride (methanesulfonyl chloride) CH3SO2Cl. |
| Triflyl | trifluoromethanesulfonyl | Tf | |
| Tresyl | 2,2,2-trifluoroethyl-1-sulfonyl | ||
| Dansyl | 5-(dimethylamino)naphthalene-1-sulfonyl | Ds | Dansyl chloride |
