Product Introduction:

Chemical Properties WHITE TO LIGHT YELLOW CRYSTALLINE POWDER

Uses Treatment with strong base yields the ylide which adds to the carbonyl group of ketones1 and aldehydes2,3 to give epoxides. Also adds preferentially to the double bond of α,β-unsaturated esters to give cyclopropyl esters.4,5

Uses Trimethylsulfoxonium Iodide is used to synthesize methylene-transfer reagents that are used in the preparation of epoxides.

Uses Trimethylsulfoxonium iodide is a sulfoxonium salt. It is used to generate dimethyloxosulfonium methylide by reaction with sodium hydride. The latter compound is used as a methylene-transfer reagent, and is used to prepare epoxides.
