1,2-Bis(diphenylphosphino)ethan

Descrição:

1,2-Bis(diphenylphosphino)ethan, allgemein als DPPE bekannt, ist ein bidentater Ligand, der in der Koordinationschemie und Katalyse weit verbreitet ist. Er weist zwei Diphenylphosphino-Gruppen auf, die an einem zentralen Ethan-Rückgrat befestigt sind, was ihm ermöglicht, Metallionen effektiv zu chelatisieren. DPPE zeichnet sich durch seine Fähigkeit aus, verschiedene Übergangsmetalle zu stabilisieren und deren Reaktivität in katalytischen Prozessen, insbesondere bei Hydrierungs- und Kreuzkupplungsreaktionen, zu erhöhen. Die Verbindung ist typischerweise ein weißer bis leicht offener fester Stoff bei Raumtemperatur und ist in organischen Lösungsmitteln wie Dichlormethan und Toluol löslich. Ihre Struktur trägt zu ihren sterischen und elektronischen Eigenschaften bei, was sie zu einem wertvollen Liganden bei der Synthese von Metallkomplexen macht. Darüber hinaus kann DPPE je nach Metallzentrum unterschiedliche Koordinationsmodi aufweisen, die die Gesamtgeometrie und Reaktivität der resultierenden Komplexe beeinflussen. Sicherheitsvorkehrungen sollten beim Umgang mit DPPE getroffen werden, da es gesundheitliche Risiken darstellen kann, wenn es verschluckt oder eingeatmet wird.
