Research Progress in the Application of Supported Functional Ionic Liquids in Organic Transformations

Abstract

Ionic liquids (ILs) have been widely used because of their excellent physical and chemical properties, and environment-friendly properties. However, the high viscosity of ILs causes difficulties in post-reaction separation and low recyclability. As the combination of ionic liquids with a variety of solid materials, supported functional ILs (SFILs) have the coupled advantages of ILs and loaded materials. It has a wide range of applications in the field of catalysis because of its high recovery performance, green economy and high efficiency. This paper mainly reviews the recent achievements over SFILs in respects of the preparation of ILs supported on various carriers like magnetic nanoparticles, graphene oxide, molecular sieves, organic-metal skeleton etc., the applications as the heterogeneous catalysts to organic transformations, and the understanding of the catalytic mechanism.
