Synthesis, spectroscopic, and thermal studies of azo compounds from luminol and procaine with acetylacetone and their complexes

Abstract

This The study entails the synthesis of two newly synthesized azo dyes luminol and procaine with acetylacetone (N1 and N2 correspondingly) .Elementalanalysis,1HNMR, T.G.A, and FTIR. have all been used to characterize dyes. These new dyes were reacted with Cpper and Nikel ionin 1:2 molar ratios to form of complexes of metals (II) with a general stoichiometry; CuL2, and NiL2 in complexes., FT IR, as well as the corresponding metal (II) complex, were used to characterize them. The dye acts as a bidentate ligand, according to elemental analysis and spectral results.The thermal properties of these compounds were investigated using thermogravimetric analysis (TGA). Thermal decomposition of these compounds is a process that occurs in stages.
