Procedure

A 0.25 l flask with a stirrer following the wall and a gas inlet tube was filled with hydrogen chloride gas. 73 g of 1,2-dimethyl-4-isopropenylbenzene were then added drop-wise at -5° to -10° C. with vigorous stirring in the course of 30 minutes, hydrogen chloride being re-added. The absorption of gas was complete 5 minutes after the end of the dropwise addition. Hydrogen chloride was stripped off from the reaction product under reduced pressure (35° C./0.8 mbar) and 89.6 g (98.2% of theory) of 1,2-dimethyl-4-(α-chloroisopropyl)benzene were obtained, m.p.: -20° to -19° C., decomposition at >50° C./1 mbar with elimination of HCl.
