    Applicable Fields:

    2-bromo-1-phenyl-1-pentanone is a derivative of valerone. It can be used as pharmaceutical intermediates.
    At room temperature, 16.2g (0.1mol) of phenopentanone and 30.9g (0.3mol) of sodium bromide were added into a 500mL round-bottomed flask, and after stirring well, 24g (0.2mol) of 30% hydrochloric acid was added, and 19g (0.15mol) of 30% hydrogen peroxide was slowly added. After the drop, the reaction was continued for 1~2 hours.
