Zeolites and other available solid acids have been successfully applied to initiate reactions, which were earlier recognised to involve superelectrophilic intermediates and thus required excess of superacids to be carried out.

When activated in the CF3SO3H/SbF5 acid system maleimide (1) and phthalimide (2) undergo selective ionic hydrogenation with cyclohexane to give 1,5-dihydropyrrol-2-one (3) and phthalimidine (11), respectively. When treated with aluminum halides, N-phenylmaleimide (4) reacts with cyclohexane to give N-phenylsuccinimide (5), whereas 2 still gives 11. Imide 1 also condenses with benzene in trifluoromethanesulfonic
