Sulfonyl

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. 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.
