research deals with preparating a new heterocyclic compounds and new derivatives for pyrazole -3-one, via tow steps: The first step of this study includes preparation new azo compounds for 3-chloro aniline and 3- Bromo aniline by coupling reactions of diazonium salt with ethyl aceto acetate. The Second step includes the cyclization of the new derivatives with the compounds phenyl hydrazine and 2,4- dinitro phenyl hydrazine . Thin layer chromatography were used to follow the chemical reaction and to characterize the new derivatives by using FT-IR and C.H.N. techniques, the results proved the correctiness of the chemical structures for the prepard derivatives .
