4′-Bromo-3-chloropropiophenone, a halogenated propiophenone derivative, is also known as 1-(4-bromophenyl)-3-chloro-1-propanone. Its molecular geometry has been studied based on density functional theory (DFT) calculations, FTIR and FT Raman spectra. | [Flammability and Explosibility]
Notclassified | [Synthesis]
The general procedure for the synthesis of 4'-bromo-3-chloropropiophenone from bromobenzene, compound (CAS:161386-38-5) and 3-chloropropionyl chloride was as follows: first, a solution was prepared by dissolving 3-chloropropionyl chloride (15 mL) in methylene chloride (10 mL). Subsequently, the solution was slowly added to a stirring suspension of aluminum chloride (20.1 g) in methylene chloride (35 mL) and the mixture was stirred at room temperature for 15 minutes. Next, the dichloromethane (10 mL) mixture of bromobenzene (15 mL) was added in batches over a period of 1 hour. After addition, the reaction mixture continued to be stirred at room temperature for 16 hours. Upon completion of the reaction, the mixture was quenched by pouring it into a mixture of ice and 1N aqueous hydrochloric acid. The organic phase was separated, washed sequentially with water and saturated aqueous sodium bicarbonate, dried (using MgSO?), and the solvent evaporated. Finally, the residue was purified by column chromatography using a 15:1 mixture of petroleum ether and ethyl acetate as eluent to afford the target product 4-bromophenyl 2-chloroethyl ketone (27.9 g, 85% yield). | [References]
