1-(4-chlorophenyl)-2-phenoxyethanone

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: A mixture of 23.3 g. (0.1 mol.) of α-bromo-p-chloroacetophenone, 10.0 g. (0.1 mol.) of phenol and 14.5 g. (0.1 mol.) of potassium carbonate in 65 ml. of dry acetone is refluxed for 12 hours. The reaction mixture is cooled, poured into 500 ml. of water and the precipitate formed is collected by filtration and recrystallized from ethanol to give α-phenoxy-p-chloroacetophenone. A mixture of 23.3 g The reaction mixture is cooled poured into 500 ml is collected by filtration recrystallized from ethanol

実験手順: To 28.4 g (213 mmole) of anhydrous potassium carbonate suspended in 100 ml of methyl ethyl ketone was added 20 g (213 mmole) of phenol and 47 g (201 mmole) of 2-bromo-4'-chloroacetophenone. The reaction mixture was refluxed for 2.5 hours, cooled, concentrated in vacuo, partitioned between diethyl ether and water, washed with dilute aqueous sodium hydroxide, washed with brine, dried over anhydrous magnesium sulfate, filtered, and concentrated in vacuo to yield 25 g of 2-phenoxy-4'-chloroacetophenone, a white solid, mp 80°-83° C. The reaction mixture was refluxed for 2.5 hours cooled concentrated in vacuo partitioned between diethyl ether and water washed with dilute aqueous sodium hydroxide washed with brine dried over anhydrous magnesium sulfate filtered concentrated in vacuo
