Abstract

original image

Andersherum: 1H- und 13C-NMR-Spektroskopie an isotopenmarkierter Glucose offenbart, dass in Gegenwart des Zinn-haltigen Zeoliths Sn-Beta die Isomerisierung von Glucose in Wasser über eine intramolekulare Hydridverschiebung (siehe Schema) und nicht etwa über einen Protonentransfer abläuft. Dies ist der erstmalige Nachweis, dass Sn-Beta in rein wässriger Umgebung als eine Lewis-Säure agiert.
