General description

Trimethylsulfonium iodide is commonly used as a methylating agent in organic synthesis.

Application

Treatment with strong base yields the dimethylsulfonium methylide which reacts in-situ with the carbonyl group of ketones to form epoxides or allylic alcohols.

Gas-liquid chromatography of cellular fatty acids is a useful tool for the identification of bacteria. Derivatization of bacterial fatty acids to methyl esters by conventional techniques is usually time-consuming and complicated. A new one-step technique using trimethyl-sulfonium hydroxide allows the
