Methyl triflate → HCID 18780403, compound

Participants

Reaction Steps

10.0 g (37.5 mM) of 9-butylthioanthracene was dissolved in approximately 100 mL heptane. To this was slowly added 6.2 g (4.3 mL, 37.8 mM) of methyl trifluoromethanesulfonate. There was a slight color change due to local orange color produced on addition, no exotherm, and haziness after a short time. The reaction was left to stir over the weekend during which time a precipitate formed. The reaction was cooled in an ice bath, then filtered and rinsed with hexanes, then air dried. This material was recrystallized from IPA, filtered, then dried in a 65° C. vacuum oven overnight to yield 2.7 g of 9-anthryl n-butyl methyl sulfonium triflate.
