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 . (2025). 9780471720911, John Wiley & Sons. ISBN 9780471720911
Sulfonyl groups can be reduced to the sulfide with diisobutylaluminium hydride (DIBALH). Lithium aluminium hydride () reduces some but not all sulfones to sulfides.
In inorganic chemistry, when the group is not connected to any carbon atoms, it is referred to as sulfuryl.
