Highly regioselective formation of 1,1-diphenylpropane was observed when copper(I) or (II) chlorides was added to the aluminium chloride-catalyzed reaction of benzene with 1-phenyl-1-propanol.In the reaction with 1-phenyl-2-propanol, the addition of copper salts increased the formation of 1,1-diphenylpropane.The addition of decalin diminished the alkylation reaction to give a reduction product.
