H. Nur et al., Phase-boundary catalysis: a new approach in alkene epoxidation with hydrogen peroxide by zeolite loaded with alkylsilane-covered titanium oxide, CHEM COMMUN, (22), 2000, pp. 2235-2236
An NaY zeolite, modified with partly alkylsilane-covered titanium oxide and
located at the boundary between aqueous and organic phases (a phase-bounda
ry catalyst), acts as a catalyst for alkene epoxidation without stirring or
the addition of a co-solvent to drive liquid-liquid phase transfer.
