Synthesis, X-ray analysis, specific electric conductivity study and antioxidant activity of novel compound based on 3-(1-phenyl-2,3-dimethylpyrazolone-5)azopentadione-2,4

A reagent 3-(1-phenyl-2,3-dimethylpyrazolone-5)azopentadione-2,4 was synthesized and isolated into crystalline form based on 4-amino-antipyrine and acetylacetone. Subsequently, 2 molecules of 3-(1-phenyl-2,3-dimethylpyrazolone-5)azopentadione-2,4 were cross-linked with ethylenediamine and a novel reagent 4-((E)-(2-((2-((1R)-2-(1,5-dimethyl-3-oxo-2-phenylpyrazolidin-4-yl)-4,4,5-trimethyl-4,5-dihydro-1H-1^λ4,2^λ4,3-triazol-1-yl)ethyl)amino)-4-oxopentan-3-yl)diazenyl)-1,5-dimethyl-2 phenylpyrazolidin-3-one.

Single crystals of the resulting product were obtained and its main characteristics were studied. Using X-ray diffraction analysis, the structure of the synthesized product was studied and the parameters of the crystal cell were determined. The stability constants and specific electric conductivity of resulting complexes of R₂ with Fe³⁺, Cu²⁺, Cd²⁺, Zn²⁺, Co²⁺, Mn²⁺, Ni²⁺ ions were calculated.

The antioxidant properties of the synthesized compounds were investigated in model reactions using the kinetic method. It was found that the synthesized compounds are effective inhibitors of hydrocarbon oxidation.
