    • A process of effecting an acid catalyzed reaction wherein a reactant capable of undergoing an acid catalyzed reaction is contacted with an acid functionalized organically-bridged polysilsesquioxane catalyst where all of the acid functionality is covalently bonded to the organic portion of an organically-bridged polysilsesquioxane framework has been developed. The acid functionalized organically-bridged polysilsesquioxane is formed by polymerizing a monomer through sol-gel processing to form an organically-bridged polysilsesquioxane, reacting an acid group onto the organic portion of the organically-bridged polysilsesquioxane, and recovering the acid functionalized product. An embodiment of the invention is where the acid catalyzed reaction is the hydration of olefins, alkylation, acylation, isomerization, or aldol condensation/elimination. A specific embodiment of the invention is effecting the aldol condensation/elimination reaction of acetone with itself to form mesityl oxide by contacting the acetone with an effective amount of sulfonated phenylene-bridged polysilsesquioxane.
