This literature review concerned with antipyrine compound . Antipyrine compound is very important compound in many chemistry fields such as in coordination chemistry , analytical chemistry as a reagent which continuously identified for possible uses and applications in several fields beside to pharmacological , medical and industrial fields. Keywords : field , antipyrine , pyrazolone , azo , Schiff , ligand , complex

Bis oxadiazole – azo ligands were synthesized via many chemical reactions and steps represented by reaction between diamine aromatic compound with concentration hydrochloric acid and sodium nitrite in azotation reaction as a first step , then the second step involved coupling step to yield mainly compound containing di active groups , which will react with semicarbazide in cyclization step to formation first ligand , after that preparation other ligands through various reaction like insertion reaction to yield second ligand , azotation reaction to yield third ligand and substitution reaction like fourth and fifth ligands. The prepared ligands have been identified by spectral techniques like (1H NMR , FT.IR and UV-Visible spectra) with chemical studies like thermal behavior , physical properties , TLC – Paper , and biological studying like microbial assay.

Aldamine – heterocyclic ligands have been prepared through condensation step to formation aldamine compound as a starting compound for production all ligands in this study, which is used in cyclization conditions for formation ligand [1], ligand [2] and ligand [3], but ligand [4] was prepared by azotation reaction, then ligand [5] prepared by formation of cyclic compound. Aldamine – heterocyclic ligands have been characterizedwith spectralmethodsrepresented by (1H NMR, FT.IR and UVVisible spectra) with other studies such as thermoanalysis, and bacterial assay for all Aldamine – heterocyclic ligands. Key words : Imide, cycle, azo.
