Synthesis
2-(3-Fluorophenyl)acetaldehyde was synthesized by oxidation reaction using 3-fluorophenethyl alcohol as starting material. The steps were as follows: 1. 3-Fluorophenyl ethanol was reacted with an oxidizing agent (e.g., PCC or Swern oxidizing reagent) in a suitable solvent at 0 °C to room temperature. 2. After completion of the reaction, the target product, 2-(3-fluorophenyl)acetaldehyde, was obtained by extraction and purification by column chromatography. This synthetic route is efficient and selective and is suitable for laboratory scale preparation.
