실험 절차

DE 29 52 719 likewise describes the iron chloride-catalyzed Friedel-Crafts alkylation of 2-methyl-3-phenylpropanol. In cyclohexane or dichloroethane as solvent, a yield of 84-86% of 2-methyl-3-(4-tert-butylphenyl)propanol was obtained. The formation of the m-isomeric compound (2-methyl-3-(3-tert-butylphenyl)propanol), was not demonstrated. A disadvantage of the described Friedel-Crafts alkylations is the small amount of the m-isomeric compound formed (m:p ratio is max. 1:5).
