-Bromostyrene is an ,-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.-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-,-difluoro-4-phenyl-3-butenoate and 1,3-diphenyl-1-butene. It may be used in the synthesis of -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 -but-2-enolactone by reacting with nickel carbonyl in the presence of alkynes.
