CLEAR YELLOWISH TO BROWN LIQUID | [Occurrence]
Apparently has not been reported to occur in nature. | [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. | [Flammability and Explosibility]
