Modern Friedel-Crafts Chemistry. Part 24. Alkylation of Benzene with 1,2-Dibromo-3-chloro-2-methylpropane in the Presence of Lewis and Bronsted Acid Catalysts
The major alkylation products of benzene with 1,2-dibromo-3-chloro-2-methylpropane are 1-X-2-methyl-3,3-diphenylpropane (X = Cl, Br) with AlCl3 and 1,4-bis-(1-bromo-3-chloro-2-methylpropyl)benzene with AlCl3-CH3NO2 or K10 montmorillonite (K10 Clay); minor products include di- and tri-phenylated butanes and/or 2-methyl-1-phenylindane.
