An efficient method for the preparation of chiral ionic liquids based on (1 R ,2 S )‐(−)‐ephedrinium salts under solvent‐free conditions and microwave activation is described. The influence of non‐specifically thermal microwave effects − consistent with mechanistic considerations − is discussed. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
