Abstract

U wie ungewohnt: Der Austausch von C5Me5 gegen einen „weichen“ PNP- Pinzettenliganden mit besonderen elektronischen und sterischen Eigenschaften erzeugte neue Reaktivitäts- und Strukturmuster in der Actinoidenreihe (siehe Bild, py–O=Pyridin-N-oxid). Die neuen Liganden unterstützen nicht nur niedervalente Uranverbindungen, sondern auch hochvalente Uran(VI)-Spezies.
