WHITE TO YELLOWISH CRYSTALLINE SOLID | [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 | [reaction suitability]
reaction type: C-C Bond Formation | [Purification Methods]
Crystallise the iodide from EtOH. [Emeleus & Heal J Chem Soc 1126 1946, Swain & Kaiser J Am Chem Soc 80 4089 1958, Borredon et al. J Org Chem 55 501 1990, Bouda et al. Synth Commun 17 503 1987.] |
