2-Bromo-4-methylbenzaldehyde

824-54-4

General method: benzyl alcohol substrate (2-bromo-4-methylphenyl) methanol (0.2 mmol), FeCl3-6H2O (0.002 mmol, 5.4 mg) and triphenylmethanol (0.2 mmol, 52 mg) were mixed in a dry reaction vessel. Subsequently, the reaction mixture was heated at 55 °C for 1 h under microwave radiation. Upon completion of the reaction, the crude product was purified by fast column chromatography to afford the target product 2-bromo-4-methylbenzaldehyde.

General procedures for the synthesis of benzaldehydes
General procedure: The benzyl alcohols substrates (1a-1p) (0.2mmol), FeCl3·6H2O (0.002mmol, 5.4mg) and triphenylmethanol 2 (0.2mmol, 52mg) were mixed in a dried vessel. Then the reaction was irradiated under the microwave at 55°C for 1h. The crude mixture was purified by a flash column chromatography to afford the benzaldehydes (4a-4p).
