Can be used as a pharmaceutical intermediate. At room temperature, 16.2g (0.1mol) of benzophenone and 30.9g (0.3mol) of sodium bromide were added to a 500mL round bottom flask, respectively. After stirring evenly, 24g (0.2mol) of 30% hydrochloric acid was added, and 19g (0.15mol) of 30% hydrogen peroxide was slowly added dropwise. After the dropwise addition was completed, the reaction was continued for 1-2 hours. After TLC monitoring of the reaction was completed, stirring was stopped, and the layers were allowed to stand. The organic phases were washed separately with saturated sodium carbonate and saturated saline solution, combined, concentrated, and dried over anhydrous magnesium sulfate to obtain 2-bromo-1-phenyl-1-pentanone, a bright yellow oily liquid with a yield of 95% and a purity of 98% (HPLC method).
