WebYou have to use higher temperatures, and then you get a mixture of 1,2- and 1,4-disubstituted benzenes. The 1,4-isomer will predominate because two large groups next to each other will have steric interference. Next you would get 1,2,4-trisubstituted and then 1,2,4,5-tetrasubstituted. Each step requires more vigourous conditions. WebElectrophilic aromatic substitution of benzene takes place in the presence of AlCl3 or FeCl3. These two act as Lewis acids as well as catalysts.
