Trifluorometansolfonato di (1,1-dimetiletil)dimetilsilile

Descrizione:

Trifluorometansolfonato di (1,1-dimetiletil)dimetilsilile, con numero CAS 69739-34-0, è un composto chimico caratterizzato dalla sua struttura unica che include un gruppo sililico e un moiety di trifluorometanosulfonato. Questo composto appare tipicamente come un liquido incolore a giallo pallido ed è noto per la sua reattività, in particolare nelle reazioni di sostituzione nucleofila. La presenza del gruppo trifluorometanosulfonato conferisce forti proprietà elettrofile, rendendolo un reagente utile nella sintesi organica, specialmente per l'introduzione di gruppi sililici in vari substrati. Il suo componente dimetilsililico ne migliora la stabilità e la solubilità nei solventi organici. Inoltre, il composto è sensibile all'umidità e deve essere maneggiato in condizioni anidre per prevenire l'idrolisi. Le precauzioni di sicurezza sono essenziali quando si lavora con questa sostanza, poiché può comportare rischi per la salute se inalata o a contatto con la pelle. In generale, Trifluorometansolfonato di (1,1-dimetiletil)dimetilsilile è uno strumento prezioso nella chimica organica sintetica, in particolare nel campo delle reazioni di sililazione.

tert-Butyldimethylsilyl trifluoromethanesulfonate is a nucleophilic reagent that forms an addition product with metal carbonyls. It can be used for the synthesis of indacaterol maleate, which is a phosphite prodrug for the treatment of asthma and chronic obstructive pulmonary disease. Tert-butyldimethylsilyl trifluoromethanesulfonate has been shown to catalyze asymmetric hydrogenation reactions in the presence of ammonia as a chiral auxiliary. This reagent has also been shown to inhibit the growth of bacteria and fungi through its ability to inhibit protein synthesis.
