Sulfoxidation

in chemistry, sulfoxidation refers to two distinct reactions.
In one meaning, sulfoxidation refers to the reaction of alkanes with a mixture of sulfur dioxide and oxygen. This reaction is employed industrially to produce alkyl sulfonic acids, which are used as surfactants. The reaction requires UV-radiation.[1]
- RH + SO2 + ½ O2 → RSO3H
The reaction favors secondary positions in accord with its free-radical mechanism. Mixtures are produced. Semiconductor-sensitized variants have been reported.[2]
Sulfoxidation can also refer to the oxidation of a thioether to a sulfoxide.
- R2S + O → R2SO
A typical source of oxygen is hydrogen peroxide.[3]
