Trimethylsulfoxonium iodide is a sulfoxonium salt. It is used to generate dimethyloxosulfonium methylide by reaction with sodium hydride.[1] The latter compound is used as a methylene-transfer reagent, and is used to prepare epoxides.
This compound is commercially available. It may be prepared by the reaction of dimethyl sulfoxide and iodomethane:[2]
- (CH3)2SO + CH3I → (CH3)3SO+I−
