2-乙氧基-1-萘硼酸

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

实验步骤: In the atmosphere of argon, 22.7 g of 2-ethoxynaphthalene-1-boronic acid, 30.0 g of 2-fluoro-5-bromoiodobenzene, 2.31 g of tetrakistriphenylphosphine palladium (0), 300 mL of toluene and 150 mL of an aqueous 2M solution of sodium carbonate were placed in a flask, and the resulting mixture was stirred with heating under reflux for 8 hours. After cooling to room temperature, the reaction solution was extracted with toluene. An aqueous phase was removed, and then, an organic phase was washed with saturated saline. The organic phase was dried with magnesium sulfate, and concentrated. Residues were purified by means of silica gel column chromatography, whereby 24.1 g (yield: 70%) of 2-ethoxy-1-(2-fluoro-5-bromophenyl)naphthalene was obtained. with heating under reflux for 8 hours the reaction solution was extracted with toluene An aqueous phase was removed an organic phase was washed with saturated saline The organic phase was dried with magnesium sulfate concentrated Residues were purified by means of silica gel column chromatography
