Organo-bridged silsesquioxane titanates for heterogeneous catalytic epoxidation with aqueous hydrogen peroxide were synthesized through the acid-catalyzed hydrolysis and co-condensation of organotrialkoxysilane monomers and α,ω-bis(trialkoxysilyl) alkane cross-linkers in ethanol–water solution, with subsequent titanium grafting. These hybrid catalysts show high activity and selectivity in the epoxidation...
