Description
Summary:A sulfonyl‐containing ammonium‐based Brønsted acid ionic liquid was prepared and used as a liquid heterogeneous catalyst for organic reactions. The unique macroscopic phase heterogeneity of the IL in the reaction system not only ensures an excellent catalytic activity of the IL catalyst but also avoids the use of organic reaction solvents. The catalyst system is applicable for a wide range of reactions. Brains not Brønsted: Sulfonyl‐containing ammonium‐based Brønsted acid ionic liquids (ILs) are prepared and used as liquid heterogeneous catalysts for organic reactions under solvent‐free conditions. The sulfonyl group endowed these ILs with unique macroscopic phase heterogeneity in the reaction system, ensuring outstanding catalytic activities of the ILs. These catalytic systems are applicable in a wide range of acid‐catalyzed reactions.
