反应详情

To 30 ml of dimethylformamide were added 7.0 g of 4-isopropenylphenol, 6.1 g of 1-fluoro-2-chloroethane and 8.7 g of potassium carbonate. With stirring, they were reacted at 120° C. for 4 hours. The reaction mixture was cooled to room temperature, and poured into water. The mixture was then extracted with toluene. The toluene layer was washed with water and dried over anhydrous sodium sulfate. Toluene was evaporated under reduced pressure to give 9.0 g of crude 4-(2-fluoroethoxy)isopropenylbenzene.
