Chemische Eigenschaften
CLEAR YELLOWISH TO BROWN LIQUID
Occurrence
Apparently has not been reported to occur in nature.
Verwenden
Beta-Bromostyrene, cis + trans is an important raw material and intermediate used in organic Synthesis, pharmaceuticals, agrochemicals and dyestuff.
synthetische
By the action of aqueous alkali on cinnamic acid dibromide.
Allgemeine Beschreibung
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.
