Graphical Abstract

Nicht Folge-, sondern Konkurrenzreaktionen sind die Oxidation von Styrol zu Styroloxid und die Bildung von Phenylacetaldehyd (PADH). In-situ-NMR- und -EPR-spektroskopische Untersuchungen der Styroloxidation an TS-1-Zeolithen (siehe Bild) zeigten, dass Brønsted-Säure-Funktionen als aktive Zentren benötigt werden, um eine Halbacetal-Zwischenstufe in PADH umzuwandeln.
