Hydrochloric Acid → (1-Chloro-1-methylethyl)benzene

Participants

Reaction Steps

183 g of α-methyl styrene, dissolved in 600 ml of methylene chloride, were reacted with hydrogen chloride at a temperature of from -12 to -10° C. to yield α-cumyl chloride. The resulting solution was added dropwise at a temperature of -10° C. to a mixture of 3 g of anhydrous aluminum trichloride, 12 g of anhydrous iron trichloride, 0.5 g of phosphorus pentoxide and 1800 ml of methylene chloride in the course of 60 minutes, and the mixture was then stirred at -10° C. for a further 4 hours. To terminate the reaction, the reaction mixture was poured into 6 liters of water at room temperature.
