Sintetizamos tribrometo de quinolina suportado em sílica, que mostrou ser um reagente de bromação eficiente, estável e reutilizável para a monobromação regiosseletiva de aminas aromáticas. Esse processo tem a vantagem de apresentar alto rendimento sob condições moderadas e usando procedimentos experimentais simples.Silica-supported quinolinium tribromide was synthesized and found to be an efficient, stable, and recoverable solid brominating reagent for the regioselective monobromination of aromatic amines. This protocol has advantages of high yield, mild condition and simple work-up procedure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
