Beta-Bromostyrene - 2

Application of Beta-Bromostyrene:

Beta-Bromostyrene or β-Bromostyrene is used in the one-pot method for the preparation of cinnamonitriles. It is 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.
