Vicinal bromoamine derivative belongs to an important class of difunctionalization compounds. New synthetic method and new vicinal bromoamine derivatives are eagerly desired. Thus, a new one-pot protocol for the synthesis of vicinal bromoamines from β,β-dicyanostyrene derivatives/amides/N-bromo-succinimide was developed. In the presence of anhydrous K2CO3, β,β-dicyanostyrenes reacted smoothly with amides and N-bromo-succinimide (NBS) to generate the vicinal bromoamine compounds in good to excellent yield (up to 93% yield) at room temperature without the protection of inert gas in CH2Cl2. 13 different structural β,β-dicyanostyrene derivatives reacted with 7 different structural amides (acrylamide, acetamide, valeramide, isobutyramide, benzamide, 4-nitrobenzamide, ethylurethanm) and NBS have been investigated in this work. The results indicated that the method is not only widely subjected to β,β-dicyanostyrene, but also suitable for the different type of amide. The structures of all the products were confirmed by their nuclear magnetic resonance spectroscopy (NMR), infrared spectra (IR) and high reso-lution mass spectrometry (HRMS), and the possible reaction mechanism was proposed.

Key words: vicinal bromoamine, β,β-dicyanostyrene derivative, amide, N-bromo-succinimide
