1-(2-乙氧基-2-氧代乙基)四氢-1H-噻吩溴酸盐

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Tetrahydrothiophene (10 g, 113 mmol) and ethyl bromoacetate (13 mL, 113 mmol) were taken in acetone (50 mL) and stirred at room temperature for 3 days. The precipitate was filtered, washed with acetone and air dried to get 1-(2-ethoxy-2-oxoethyl)tetrahydro-1H-thiophenium bromide (23 g, yield 82%), which was carried through without further purification. The precipitate was filtered washed with acetone and air dried
