• 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 was used in the following studies:
• Structure-activity relationships (SAR) study of the chemical and biochemical properties of the vinyl group of styrene.
• Synthesis of silsesquioxanes (SQ) having 4-bromostyrenyl substituents.
• To investigate the photochemical growth of Br-terminated self-assembled monolayers (SAMs) on Si(111).
• Synthesis of poly(1,4-phenylenevinylene) via Heck reaction.
• Synthesis of nitroolefins via alkene cross-metathesis.
