The first experimental evidence for the formation of ordered three-dimensional structures in solutions of organometallic complexes in a thin film of supported ionic liquid was obtained. The ordering effect leads to drastically reduced mobility of ionic liquid and complex molecules.
The concept of immobilising organometallic complexes in a thin film of supported ionic liquids was utilised to synthesise novel bi-functional catalysts combining soft Lewis acidic and strong Brønsted acidic functions; the materials showed exceptional catalytic activity for the addition of aniline to styrene, providing the Markownikoff product under kinetically controlled conditions and mainly the anti-Markownikoff product in the thermodynamic regime.

The direct addition of NH across a CC multiple bond (hydroamination) was efficiently catalysed in a liquid-liquid two-phase system. The latter comprised a polar catalyst phase of Zn(CF3SO3)2 in the ionic liquid 1-ethyl-3-methylimidazolium trifuoromethanesulfonate and a substrate mixture in heptane. The possibility of catalysing different hydroamination reactions continuously was demonstrated.
