Abstract

The invention relates to the field of chemistry, in particular to derivatives of 2-nitro-4,5-diarylimidazole that can be used as biologically active compounds, catalysts, etc.Summary of the invention consists in that it is proposed a process for producing 2-nitro-4,5-diphenylimidazole by the reaction of demetalation with a mineral acid at pH≤ 2 in aqueous medium of coordinative compounds of Co(II), Ni(II) and Zn(II) with 2-nitro-4,5-diphenylimidazole. After neutralization of the resulting mixture the target compound is extracted with a water-immiscible solvent and is isolated from the extract.The initial coordinative compounds can be obtained at the interaction of 4,5-diphenylimidazole with the nitrate of the corresponding metal in solvothermal conditions with in situnitration of heterocycle.
