Trifluorometansolfonato di bismuto(III)

Descrizione:

Trifluorometansolfonato di bismuto(III), con il numero CAS 88189-03-1, è un composto inorganico caratterizzato dal suo centro di bismuto coordinato con ligandi trifluorometanosulfonato (triflate). Questo composto appare tipicamente come un solido bianco a bianco sporco ed è noto per la sua solubilità in solventi organici polari. Trifluorometansolfonato di bismuto(III) è notevole per le sue proprietà di acido di Lewis, rendendolo utile come catalizzatore in varie reazioni organiche, in particolare nella sintesi di molecole complesse. I suoi gruppi triflate migliorano la sua reattività e stabilità, permettendogli di partecipare a sostituzioni aromatiche elettrofile e altre trasformazioni. Inoltre, i composti di bismuto sono spesso considerati alternative meno tossiche ai catalizzatori a base di metalli pesanti, il che aumenta il loro fascino sia in ambienti industriali che di laboratorio. Il composto deve essere maneggiato con cura, come tutte le sostanze chimiche, e devono essere osservate le appropriate misure di sicurezza per ridurre al minimo l'esposizione.

Bismuth(III) trifluoromethanesulfonate

CAS: 88189-03-1

Trifluoromethanesulfonic acid is a strong acid, which is typically used as a catalyst in acylation reactions. It is also used to catalyze epoxidation and amination reactions. Trifluoromethanesulfonic acid can be prepared by the careful addition of hydrochloric acid to trifluoroacetic anhydride at 0°C. The reaction of this acid with alcohols produces an ester and hydrogen chloride gas. Trifluoromethanesulfonic acid reacts with amines to produce an amide and hydrogen fluoride gas. Trifluoromethanesulfonic acid is also capable of removing a hydroxyl group from carboxylic acids or phenols, which can lead to the formation of aldehydes or ketones respectively. Trifluoromethanesulfonic acid is also known for its ability to efficiently catalyze allylation and triflation reactions, respectively.
