Allyl bromide (3-bromoprop-1-ene) is an organic halide. Its refractive index is 1.4697 (20 °C, 589 nm). Allyl bromide is an alkylating agent used in synthesis of polymers, pharmaceuticals, allyls and other organic compounds. Physically, allyl bromide is a clear, viscous, sticky liquid with an intense and pleasant sweet smell. In addition, allylzinc bromide may be produced by treating this compound with elemental zinc. Unlike most organometallic reagents, which are pyrophoric in air and destroyed by water, allylzinc bromide is stable in aqueous solvents and can attack aldehydes in a Barbier-type reaction, leading to carbon-carbon bond formation.
