Abstract

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 AlCl ₃ and 1,4-bis-(1-bromo-3-chloro-2-methylpropyl)benzene with AlCl ₃ –CH ₃ NO ₂ or K10 montmorillonite (K10 Clay); minor products include di- and tri-phenylated butanes and/or 2-methyl- 1-phenylindane.
