Abstract:
Cross-coupling of aromatic aldehydes with unactivated iminescatalyzed by N,N-dimethylbenzimidazolium iodide in ethanolic sodium hydroxide solution gave α-amino ketonesin satisfactory yields. Benzoin condensation and further oxidation of the resulted aroins also occurred as side reactions.
Keywords:N,N-dimethylbenzimidazolium iodide; green catalyst; cross-coupling; unactivated imines; α-amino ketones
