| | Trimethylsulfonium iodide Usage And Synthesis |
| Chemical Properties | white to yellowish crystalline solid. Soluble in water, alcohol, tetrahydrofuran, dimethyl sulfoxide. | | Application | Trimethylsulfonium Iodide is a sulfoxonium salt. It is used to Treatment with strong base yields the dimethylsulfonium methylide which reacts in-situ with the carbonyl group of ketones to form epoxides or allylic alcohols. | | Uses | Trimethylsulfonium iodide is a salt that is usually dissolved in strong base in order to synthesize epoxides in-situ. Trimethylsulfonium iodide also has the potential to inhibit human placental diamine oxidase. | | Preparation | Trimethylsulfoxonium iodide may be prepared by the reaction of dimethyl sulfoxide and iodomethane:
(CH3)2SO + CH3I → (CH3)3SO+I
After standing overnight, the resulting solid white cake is crushed and recrystallized from absolute ethanol to give pure trimethylsulfonium iodide. | | Purification Methods | Crystallise the iodide from EtOH.
