Abstract

Keine CO-Operation: Zwei auf einem dreizähnigen Liganden basierende Single-Site-Ruthenium-Katalysatoren zeigen trotz struktureller Ähnlichkeiten einen bemerkenswerten Unterschied in ihrem katalytischen und chemischen Verhalten (siehe Bild). Die Tatsache, dass der CO-koordinierte Komplex bei der katalytischen Oxidation von Wasser gebildet wird, legt einen neuen Desaktivierungspfad des Katalysators nahe.
