Main Article Content
Abstract
This research includes the preparation of some of pyrazoline derivatives containing the azo group by one pot method through the treatment of the compound 2-hydroxy-5-(m-tolyldiazenyl) benzaldehyde with p-chlorob enzylchloride to give the compound(1) using the Williamson reaction. The compound (1) is treated with a series of ketones and with phenylhydrazine in the base medium to give new derivatives of pyrazoline (2-11). The synthesized compounds were characterized by elemental analyses and FT-IR, 1H-NMR, 13C-NMR, 13C-DEPT.
