| Application: | 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-phenylenevinylen • Synthesis of nitroolefins, via alkene cross-metathesis. |
| General description: | 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-methoxynaphthal |
