YieldReaction ConditionsOperation in experiment
92% With potassium phosphate; copper(l) iodide In tetrahydrofuran at 80℃; for 12 h; Inert atmosphere 2-bromobenzofuran. To a solution of 2-(2,2-dibromovinyl)phenol (2.8 g, 10 mmol) in tetrahydrofuran (30 mL) was added copper(I) iodide (0.1 g, 0.5 mmol) and potassium phosphate (4.2 g, 20 mmol). The reaction mixture was stirred at 80°C under nitrogen atmosphere for 12 hours. After the reaction, the mixture was poured into water (200 mL) and the mixture was extracted with ethyl acetate (200 mL). The organic phase was dried over anhydrous sodium sulfate and then filtered. The filtrate was concentrated and the residue was purified by column chromatography (silica gel, ethyl acetate/petroleum ether = 1 :20) to give the pure product 2- bromobenzofuran (1.8 g, 92percent).
