Sulfur ions | Cations | Sulfonium compounds
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 [SR3]+. Together with a negatively-charged counterion, they give sulfonium salts. They are typically colorless solids that are soluble in organic solvent. (Wikipedia).

Sulfur Ylides - Corey-Chaykovsky Reaction (IOC 42)
In this episode, I discuss sulfur ylides and the Corey-Chaykovsky reaction, which forms epoxides, aziridines, as well as cyclopropanes. On slide 8, I mistakenly say "the N parameters of ketones" but as aldehydes and ketones are electrophiles, I should have said "the E parameters". On sli
