Trirutheniumdodecacarbonyl ist eine chemische Verbindung aus der Gruppe der Metallcarbonyle.

Gewinnung und Darstellung

Trirutheniumdodecacarbonyl kann durch Reaktion von Ruthenium(III)-acetylacetonat mit Kohlenmonoxid und Wasserstoff gewonnen werden.[3]

Ebenfalls möglich ist die Darstellung durch Reaktion von Ruthenium(III)-chlorid-trihydrat-Lösung mit Kohlenmonoxid zu Carbonylchlororuthenium-Komplexen RuCly(CO)x und diesen dann weiter mit Zink und Kohlenmonoxid in Ethanol.

Eigenschaften

Trirutheniumdodecacarbonyl ist ein orangefarbener, ziemlich luft- und lichtbeständiger Feststoff. Er ist löslich in fast allen organischen Lösungsmitteln, insbesondere in Aceton, jedoch unlöslich in Wasser.[2]

Verwendung

Trirutheniumdodecacarbonyl wird als Ausgangsmaterial für Carbonyl-Cluster und als Wasserstoff-Transfer-Katalysator verwendet. Es wird zur reduktiven Carbonylierung von aromatischen Nitroverbindungen zu Carbamaten und zur allylischen Aminierung von aktivierten Olefinen durch Nitroarene verwendet.[2]
