용도4-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. It is also used to investigate the photochemical growth of Br-terminated self-assembled monolayers. It is also involved in the synthesis of silsesquioxanes.

일반 설명4-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.
