sulcation
Sulcation is a chemical term used to describe the introduction of sulfur-containing groups into a substrate, typically resulting in either a sulfonated derivative or a sulfonium salt. The term is not standardized across disciplines, and in most literature the more precise terms sulfonation or sulfonium formation are used depending on the context and mechanism.
In organic chemistry, sulfonation refers to electrophilic substitution in which a sulfonyl group is added to
In organosulfur chemistry, sulcation can describe the formation of sulfonium ions by the alkylation of sulfides
Notes on usage and safety: Sulfonation and sulfonium formation often involve corrosive reagents and exothermic steps.
