K10-montmorillonite has been tested as Friedel-Crafts catalyst in the alkylation of benzene, toluene and anisole with one or more of the alkylating agents 1-10. The reaction products consisted essentially of 1,1- and 1,2-diaryl-2-methylpropane derivatives (e.g. 11 and 12 respectively) together with side products resulting from transalkylation, monoalkylation, hvdride transfer and elimination. K 10-montmorillonite has also been used to catalyse the alkylation of naphthalene with benzyl alcohol whereby a mixture of α-and β-benzylnaphthalene is obtained. The results, explained in terms of carbocation transformations, show K 10-montmorillonite to be a mild catalyst with no subsequent side-chain isomerising ability just like FeCl3, AlCl3-CH3NO2, TiCl4 and ZrCl4.
