In organic chemistry, a sulfonium ion, also known as sulphonium ion or sulfanium ion, is a positively charged ion (a "cation") featuring three organic substituents attached to sulfur. These organosulfur compounds have the formula . Together with a negatively charged counterion, they give sulfonium salts. They are typically colorless solids that are soluble in polar organic solvent.
