Trifluorometanossulfonato de bismuto(III)

Descrição:

Trifluorometanossulfonato de bismuto(III), com o número CAS 88189-03-1, é um composto inorgânico caracterizado por seu centro de bismuto coordenado com ligantes trifluorometanosulfonato (triflate). Este composto geralmente aparece como um sólido branco a off-white e é conhecido por sua solubilidade em solventes orgânicos polares. Trifluorometanossulfonato de bismuto(III) é notável por suas propriedades de ácido de Lewis, tornando-o útil como catalisador em várias reações orgânicas, particularmente na síntese de moléculas complexas. Seus grupos triflate aumentam sua reatividade e estabilidade, permitindo que participe de substituições aromáticas eletrofílicas e outras transformações. Além disso, os compostos de bismuto são frequentemente considerados alternativas menos tóxicas a catalisadores de metais pesados, o que aumenta seu apelo em ambientes industriais e laboratoriais. O composto deve ser manuseado com cuidado, assim como todas as substâncias químicas, e medidas de segurança adequadas devem ser observadas para minimizar a exposição.

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.
