CAS 1663-45-2: 1,2-Bis(difenilfosfino)etano

Descrizione:
1,2-Bis(difenilfosfino)etano, comunemente noto come DPPE, è un ligando bidentato ampiamente utilizzato nella chimica di coordinazione e nella catalisi. Presenta due gruppi difenilfosfino attaccati a uno scheletro centrale di etano, il che gli consente di chelare efficacemente ioni metallici. Il DPPE è caratterizzato dalla sua capacità di stabilizzare vari metalli di transizione, migliorando la loro reattività nei processi catalitici, in particolare nelle reazioni di idrogenazione e accoppiamento incrociato. Il composto è tipicamente un solido bianco a bianco sporco a temperatura ambiente ed è solubile in solventi organici come il diclorometano e il toluene. La sua struttura contribuisce alle sue proprietà steriche ed elettroniche, rendendolo un ligando prezioso nella sintesi di complessi metallici. Inoltre, il DPPE può mostrare diversi modi di coordinazione a seconda del centro metallico, influenzando la geometria e la reattività complessiva dei complessi risultanti. Devono essere adottate precauzioni di sicurezza quando si maneggia il DPPE, poiché può comportare rischi per la salute se ingerito o inalato.
