摘要
Herein, we present the synthesis, the thermal and mesophormic properties of trialkyl(1,3,5-benzene)trisimidazolium salts. These salts form highly ordered rectangular columnar ionic liquid crystal phases and can be used as reaction media for Diels Alder reactions. The use of the ionic liquid crystal phase favours the formation of the intramolecular Diels Alder products, even in high concentration reaction conditions. We show that the ionic liquid crystal phase can be recycled and reused as solvent for at least 10 times, without any loss of yield or selectivity in the Diels Alder reaction.
