Descripción

Descripción general

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.

Aplicación

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.
