Abstract

original image

Doppelt wirksam: Die Synthese von Benzimidazolen durch Bestrahlung einer Alkohollösung, die ein ortho-Arylendiamin und Pt@TiO2-Nanopartikel enthält, verläuft über eine platinunterstützte photokatalytische Oxidation des Alkohols und eine katalytische Dehydrierung der Zwischenstufen auf der Oberfläche der Platinnanopartikel.
