Thioanisole → HCID 21872329, compound

Participants

Reaction Steps

To a solution of thioanisole (2.48 g, 20 mmole) in methylene chloride (20 ml), methyl trifluoromethanesulfonate (3.28 g, 20 mmole) was added dropwise at 10° C. or below, and the mixture was refluxed for 2 hours with stirring. After cooling, the reaction solution was poured into n-hexane (75 ml), and the precipitate was filtered, washed with n-hexane and dried. The resultant crude solid (5.35 g) was recrystallized from iso-propanol to give 4.8 g of dimethylphenylsulfonium trifluoromethanesulfonate as white leaflets. m.p. 106.0°-107.2° C.
