How is 2-Bromo-1-(2-fluorophenyl)ethanone (CAS: 655-15-2) typically synthesized?

2-Bromo-1-(2-fluorophenyl)ethanone is typically synthesized via a reaction of 2-bromoethanone with 2-fluorophenylboronic acid in the presence of a palladium catalyst, such as Pd(PPh3)4, in the absence of oxygen. The reaction involves a cross-coupling process, leading to high selectivity and good yield. Other methods include the direct bromination of 1-(2-fluorophenyl)ethanone using bromine, although this approach may yield lower purity products.
