1-(4-fluorophenyl)pent-4-en-1-one

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a stirred solution of 1-(4-fluoro-phenyl)-pent-4-en-1-ol (4.9 g) in dichloromethane (5 ml) was added pyridimium chlorochromate (7.033 g). The reaction mixture was stirred for 16 hours at room temperature. Silica gel was added and the solvent was evaporated. Column chromatography (SiO2; heptane/EtOAc 4:1) gave 1-(4-fluoro-phenyl)-pent-4-en-1-one (4.67 g, 96%) as a light yellow liquid.MS (EI): 178.0 ([M+H]+)), 123.0 (F—C6H4CO+) Silica gel was added the solvent was evaporated
