실험 절차

Glutaryl chloride (28.2 g; 0.167 mole) was slowly added to a mixture of anhydrous aluminum trichloride (50 g; 0.375 mole) and 250 ml benzene. The mixture was stirred vigorously in an ice/water bath. After completion of the addition, the ice/water bath was removed and stirring was continued for two hours. The solution obtained was slowly poured into a mixture of 200 g crushed ice and 40 ml concentrated aqueous hydrochloric acid. The resulting product was recovered by extraction and crystallization to produce 1,5-diphenyl-1,5-pentanedione.
