Sulfuryl chloride → Furan-3-sulfonyl chloride

Participants

Reaction Steps

In flame dried glassware under a nitrogen atmosphere to a solution of 428 mg (2.909 mmol) of 3 bromofuran in anhydrous tetrahydrofuran at -78° C. was added 2.0 mL n-butyl lithium (3.2 mmol at 1.6 molar in hexane). After 45 minutes the resultant solution was added via cannula to a 20° C. solution of sulfuryl chloride in diethyl ether (5 mL plus a 2 mL rinse). After 1 h, the reaction was quenched with 0.5N hydrochloric acid and extraced into diethyl ether. The ethereal extracts were washed with saturated brine, dried over magnesium sulfate, filtered and concentrated in vacuo to provide 158 mg of the title product. (1H) NMR (CDCl3) consistent with structure.
