The formation of strong excimers in the presence of hydroxy dicarboxylic acids could be attributed to the guest acid templated hydrogen bond induced organization of the

• in mind: to promote 'green reaction media' and most importantly to provide a highly efficient chirality transfer due to the high degree of organization of the chiral ionic liquids. Chiral solvents are reported to have been already used as a sole inducer of enantiomeric excess in organic reactions

• ionic liquids, due to their unique properties and especially their high degree of organization as chiral reaction medium in this reaction. Further investigations to provide useful insights into the understanding of the use of chiral ILs in asymmetric induction are in progress in our laboratory. The
