Acetyl chloride → HCID 14390561, compound

Participants

Reaction Steps

To a stirred mixture of 2-(2,2-dibromoethenyl)-5-(4-hydroxyphenyl)thiophene (1.0 g, 0.003 mole) and triethylamine (1.2 g, 0.08 mole) in tetrahydrofuran (20 mL) was added acetyl chloride (0.44 g, 0.0056 mole). The reaction mixture was stirred at room temperature for approximately 18 hours. The mixture was diluted with diethyl ether and washed in succession with an aqueous 5% sodium hydroxide solution, water, and an aqueous saturated sodium chloride solution. The washed mixture was dried over anhydrous magnesium sulfate and filtered. The filtrate was evaporated under reduced pressure, yielding 0.5 g of 2-(2,2-dibromoethenyl)-5-(4-acetyloxyphenyl)thiophene as a solid (mp 115°-115.5° C.).
