Application:
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.
