MALEKI, Behrooz  and  SEDIGH ASHRAFI, Samaneh. N-Bromosuccinimide Catalyzed Three Component One-Pot Efficient Synthesis of 2,4,5-Triaryl-1H-imidazoles from Aldehyde, Ammonium Acetate, and 1,2-Diketone or α-Hydroxyketone. J. Mex. Chem. Soc [online]. 2014, vol.58, n.1, pp.76-81. ISSN 1870-249X.

A simple, green, and efficient method for the synthesis of 2,4,5-triaryl-1H-imidazoles using N-bromosuccinimide (NBS) as a catalyst under solvent-free condition is described. The major advantages of the present method are: high yields, less reaction times, solvent-free conditions, easy purification of the products, environmental friendliness, and convenient operation.

Keywords : 2,4,5-Triaryl-1H-imidazoles; aldehydes; ammonium acetate; 1,2-diketone; -hydroxyketone; N-bromosuccinimide.
