Tetramethylene sulfoxide → HCID 87825836, compound

Participants

Reaction Steps

Next, 2.9 g (0.05 mol) of tetramethylene sulfoxide was added to 5.0 g (0.025 mol) of the 2-n-butoxynaphthalene and 15 g of Eaton's reagent (Aldrich), followed by 24 hours of stirring at room temperature. 200 g of water and 50 g of diethyl ether were added to the reaction mixture for separation into two layers. To the aqueous layer, 8.5 g (0.025 mol) of potassium perfluorobutanesulfonate and 100 g of dichloromethane were added, followed by one hour of stirring at room temperature. The organic layer separated was washed three times with 50 g of water, after which the solvent was evaporated off on a rotary evaporator. The oily matter was recrystallized from ethyl acetate, filtered and dried. There was obtained 13.8 g of the end compound, 2-n-butoxy-1-naphthyltetrahydrothiophenium perfluorobutanesulfonate (yield 94%).
