CAS 4039-32-1: Bis(trimetilsilil)amide di litio

Descrizione: Bis(trimetilsilil)amide di litio, con il numero CAS 4039-32-1, è un composto organolitico caratterizzato dalla sua forte basicità e nucleofilia. Presenta un catione di litio coordinato a un anione bis(trimethylsilyl)amide, che consiste in due gruppi trimethylsilyl legati a un atomo di azoto. Questo composto è tipicamente un solido bianco a giallo chiaro ed è altamente solubile in solventi non polari come esano e toluene, rendendolo utile in varie applicazioni di sintesi organica. Le sue forti proprietà basiche gli consentono di deprotonare un'ampia gamma di substrati, facilitando reazioni come la formazione di legami carbonio-carbonio. Inoltre, Bis(trimetilsilil)amide di litio è spesso impiegato come reagente nella sintesi di molecole organiche complesse e nella preparazione di intermediari contenenti litio. Tuttavia, deve essere maneggiato con cura a causa della sua reattività e del potenziale di reagire con l'umidità, il che può portare al rilascio di gas infiammabili. In generale, questo composto è uno strumento prezioso nella chimica organica sintetica e nella scienza dei materiali.
