Benzene alkylation with mono- and bicyclic olefins under the action of an inorganic ionic liquid [Et3NH]+[Al2Cl7]? with the formation of benzene cycloalkyl derivatives in 58–98% yield has been performed for the first time. It has been found that the increase in the olefin cycle size improves the selectivity with respect to monocycloalkyl derivatives.
Hydrocarbon activation. Synthesis of β-cycloalkyl (Di)nitriles through photosensitized conjugate radical addition

Photoinduced hydrogen abstraction from aliphatic cyclic hydrocarbons (C5 to C7, C12, as well as adamantane) by triplet aromatic ketones in the presence of α,β-unsaturated (di)nitriles offers a straightforward entry to the corresponding alkylated (di)nitriles via the alkyl radicals. Yields are moderate to good depending on the olefins structure (substitution in β slows down the addition to mononitriles, but with α,α-dinitriles electronic activation allows efficient alkylation also of β,β-disubstituted substrates). A tandem alkylation - cyclization process has been obtained with (1-methylpent-4-enylidene)malononitrile.
