Versuchsvorschrift

12 g (0.1 mol) cumene and 10 g (0.05 mol) triisopropylbenzene are dissolved in 150 ml of anhydrous hydrogen fluoride at a temperature between -20° and 0°. While stirring the reaction mixture at this temperature, it is saturated with boron trifluoride and stirring is continued for two hours. After workup, as in Example 5, 36% diisopropylbenzene was obtained, comprised of 99.2% of the meta and 0.8% of the para isomer.
