4-Bromostyrene
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. Uses: 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.
