Abstract

original image

Hoch spezifisch und katalytisch gelingt die Oxidation von Wasser mit dem zweikernigen Mangankomplex eines einfach negativ geladenen carboxylathaltigen fünfzähnigen Liganden (siehe Schema). Isotopenmarkierungsexperimente in Kombination mit der Membraneinlass-Massenspektrometrie ergaben, dass ein Sauerstoffatom im gebildeten O2-Molekül vom Wasser stammt und das andere vom Oxidationsmittel.
