The Lewis acidic imidazolium based ionic liquids are widely used as organocatalyst in the organic synthesis. The uses of ionic liquids for Diels-Alder reaction have been extensively done as homogeneous media with/without metal. These homogeneously operating ionic liquids are prone to problems like recovery of catalyst/ionic liquid, separation of pure products etc. To overcome those limitations, ionic liquid supported mesoporous silica can be used as a heterogeneous organocatalyst and can play important role with recyclability. The oraganosilane modified imidazolium based ionic liquid functionalized SBA-15 was synthesized directly through microwave to control the morphology and thermal stability. We assured the short channel platelet morphology by using TEM and SEM which is efficiently useful to diffusion of reactant and product. This heterogenized organocatalyst showed very good catalytic activity for the Diels Alder reaction between cyclopentadiene and ethyl acrylate under solvent free condition. With increasing the ionic liquid in SBA-15 increased conversion upto 99% at room temperature. We also compared the endo selectivity with different solvent and solvent free conditions.
