Tin-containing zeolites (Sn-Beta) are highly active materials for the isomerization of glucose into fructose in water. We demonstrate a mechanistic pathway involving an intramolecular hydride shift, confirming Lewis acidity of framework tin centers in water. ¹¹⁹Sn NMR data show that tin centers exist as isolated sites in tetrahedral coordination.
