4-Bromostyrene is a para-halogenated styrene derivative. The proton spectra of 4-bromostyrene exhibits dipolar couplings consistent with planar ground state structures, only if the torsional motion of lowest frequency occurs at about 80cm-1. It undergoes Heck reaction with 2-bromo-6-methoxynaphthalene in the presence of sodium acetate and Hermann′s catalyst in N N-dimethylacetamide to afford diarylethene.

4-Bromostyrene is widely utilized in the synthesis of nitroolefins by alkene cross-metathesis. It plays an important role in the Heck reaction to the synthesis of poly(1,4-phenylenevinylene). It is employed in the structure activity relationships (SAR) study of the chemical and biochemical properties of the vinyl group of styrene.
