(138f) Structure-Reaction Property Relationships for Lewis Acid Molecular Sieves

Lewis acidic tetravalent heteroatoms (Sn⁴⁺, Ti⁴⁺, Zr⁴⁺) isolated within silica-based molecular sieves catalyze sugar isomerization and epimerization reactions as well as Diels Alder reactions of ethylene with substituted furans. Here, I will discuss the atomic arrangements and local environments of the Lewis acid centers and their reaction properties.
