  Epoxidation of large alkenes in mesoporous titanium silicates using aqueous hydrogen peroxide is a challenge due to instability of the catalyst to water. We report an investigation into the effects of surface modification of titanium-grafted SBA-15 (Ti-SBA15) and hydrophobic titanium-grafted methyl-capped SBA-15 (Ti-MeSBA15) with fluorinated-alcohol terminated tethers. Their selectivities and yields for the epoxidation of 1-octene and cyclohexene are presented. This is an extension of the known enhancement of several oxidation reactions with aqueous hydrogen peroxide using fluorinated alcohols as solvents by hydrogen-bonding networks.
