2-(4-CHLOROPHENYL)-1-PHENYLETHANONE

The representative example of oxidative bromination is described as follows: A mixture of 1.2 g acetophenone 1a (10 mmol) and 0.121 g Cu(NO3)2'3H2O (0.5mmol) was stirred and an oxygen balloon (about 0.5-1 L) was attached to the reaction system. Then 8mol/L aqueous solution of hydrobromic acid (1.5mL, 12mmol) was added dropwise to the mixture. The reaction mixture was then stirred at 70C and monitored by TLC or GC. After the completion of the reaction, the mixture was extracted with CH2Cl2. The organic extract was first washed with 5% sodium sulfite, saturated sodium bicarbonate solution, and then water and finally dried over anhydrous magnesium sulfate. The solvent was removed under vacuum and the residue was purified by column chromatography (silica gel, petroleum ether/dichloromethane 3:1) to afford the product, alpha-bromoacetophenone (2a) in 1.81 g, yield: 91%.
