Abstract
A method for the bromination of aromatic compounds, including substituted deactivated aromatic compounds, at mild temperature conditions is disclosed. The method comprises reacting an aromatic compound with a bromination agent consisting of bromine-trifluoride and bromine at a temperature ranging between -10.degree. C. and 30.degree. C. The bromination reaction takes place instantaneously and the brominated aromatic compound is separated from the original reactant by known organic chemistry techniques.
