Ethenylene groups within the silicate framework of hybrid mesoporous ethenylene‐silica (HME) are successfully modified via a two‐step chemical modification process (see Figure) to produce a sulfonic acid‐functionalized hybrid mesoporous solid acid catalyst. The material exhibits high activity for various acid‐catalyzed reactions and can be used repeatedly without deactivation. The Diels–Alder modification described can be extended to the creation of other functional materials.
