Abstract
A method for brominating hydroxyaromatic compounds to form products, such as p-bromophenol, is disclosed. The method uses elemental bromine as the brominating agent and comprises contacting a hydroxyaromatic compound with bromine and oxygen in the presence of metal catalyst. Suitable catalysts include elemental copper, copper compounds, and compounds of Group IV–VIII transition metals.
