beta-Bromostyrene Chemical Properties,Usage,Production

Chemical Properties

CLEAR YELLOWISH TO BROWN LIQUID

Occurrence

Apparently has not been reported to occur in nature.

Uses

Perfumery.

Uses

Beta-Bromostyrene, cis + trans is an important raw material and intermediate used in organic Synthesis, pharmaceuticals, agrochemicals and dyestuff.

Uses

β-Bromostyrene was used in the one-pot method for the preparation of cinnamonitriles. It was also used in the preparation of pure ethyl Z- and E-α,α-difluoro-4-phenyl-3-butenoate and 1,3-diphenyl-1-butene. It may be used in the synthesis of β-tert-butylstyrene via cross coupling reaction with tert-butylmagnesium chloride in the presence of dichloro[1,1′-bis(diphenylphosphino)ferrocene]nickel(II) catalyst. It may also be used to prepare γ-but-2-enolactone by reacting with nickel carbonyl in the presence of alkynes.

Preparation

By the action of aqueous alkali on cinnamic acid dibromide.

General Description

β-Bromostyrene is an α,β-unsaturated aromatic halide. It can be synthesized by catalytic Hunsdiecker reaction (CHR) of cinnamic acid. It is commonly utilized as a precursor for preparing substituted alkenes, corresponding acetylenes and also in the total synthesis of natural compounds and antibiotics.
