Abstract Nine kinds of halo-substituted nitro-diphenylethers were prepared under microwave radiation. The influences of microwave power, reaction time, catalyst, and solvent on products yield were discussed. Compared with conventional methods, the presented one has the advantage of good yield, short reaction time and high reaction selectivity. The structures of all products were characterizd by IR, ¹H NMR and elemental analysis.
