Regioselective aminohalogenation of β-nitrostyrenes using NCS and NBS as nitrogen/halogen sources

Aminohalogenation reaction of β-nitrostyrenes with N -halosuccinimides ( N -chloro and N -bromosuccinimides) has been successfully conducted by using nickel acetate as a catalyst in the presence of potassium carbonate and succinimide as co-additives. The reaction was easily performed at room temperature under nitrogen gas protection to give dihalorinaed haloamino products in good to excellent yields (60%–98%). The structure has been confirmed by X-ray crystal structure analysis.
