摘要
Acidic ionic liquid was immobilized on silica-coated magnetite nanoparticles (Fe3O4@SILnP) and used as an efficient heterogeneous catalyst for the diazotization-iodination reaction of different aromatic amines under solvent-free conditions at room temperature. The diazonium salts that are formed by this catalyst are stable at room temperature and react rapidly with sodium iodide to produce aryl iodides in good to excellent yields. This method has some advantages such as low pollution, rapid access to products, simple work-up and easy separation of catalyst from the reaction mixture.
