Cornforth reagent → 1-(3-Bromo-5-fluorophenyl)ethan-1-one

Participants

Reaction Steps

To a solution of 1-(3-bromo-5-fluoro-phenyl)-ethanol (2.9 g, 13.2 mmol) in methylene chloride (150 ml) was added at room temperature pyridinium dichromate (3.98 g). The reaction mixture was stirred for 4 hours at room temperature and the solvent was removed in the presence of silica gel. The crude product was purified by chromatography over silica gel to provide 1-(3-bromo-5-fluoro-phenyl)-ethanone (1.39 g, 45%) as a light yellow solid, MS: m/e=216.1 (M+).
