CAS 1099-45-2: Acetato di etil trifenilfosforanilideno

Descrizione: Acetato di etil trifenilfosforanilideno, con il numero CAS 1099-45-2, è un composto organofosforato caratterizzato dalla sua struttura unica, che include un gruppo fosforanilidene legato a un moiety di acetato di etile. Questo composto appare tipicamente come un solido o un liquido viscoso ed è noto per il suo ruolo come reagente nella sintesi organica, in particolare nella formazione di legami carbonio-carbonio. Mostra una stabilità moderata in condizioni standard, ma può decomporsi sotto calore estremo o in presenza di acidi o basi forti. Acetato di etil trifenilfosforanilideno è spesso utilizzato nella reazione di Wittig, dove agisce come un ylide di fosfonio, facilitando la conversione di composti carbonilici in alcheni. La sua reattività è influenzata dalle proprietà donatrici di elettroni del gruppo trifenylofosfina, che ne aumenta la nucleofilia. I dati di sicurezza indicano che deve essere maneggiato con cura, poiché può comportare rischi per la salute se ingerito o inalato, richiedendo misure di sicurezza appropriate durante l'uso.
