General description

4-Bromoanisole is a useful brominating reagent. It is formed as reaction product in the reaction between HOBr and anisole. Suzuki coupling of 4-bromoanisole with phenylboronic acid catalyzed by palladium pincer complexes has been studied. Heck Reaction of 4-bromoanisole with ethyl acrylates in room-temperature ionic liquids is reported to afford ethyl 4-methoxycinnamate.

Application

4-Bromoanisole was used in the synthesis of aryl 1,3-diketones.

Reaction conditions for the three-component synthesis of aryl 1,3-diketones are reported applying the palladium-catalyzed carbonylative α-arylation of ketones with aryl bromides. The optimal conditions were found by using a catalytic system derived from [Pd(dba)2] (dba=dibenzylideneacetone) as the palladium source and

When bromide-containing waters are chlorinated, conventional wisdom typically assumes HOBr is the only active brominating agent. Several additional and often-overlooked brominating agents (including BrCl, Br2, BrOCl, Br2O) can form in chlorinated waters, albeit at generally lower concentrations than HOBr. The
