RESUMO
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.
