عنوان المقالة: Synthesis, Characterization and Corrosion Inhibition Study of New Heterocyclic Compounds and Schiff Base with [Co (II), Ni (II), Cu (II) and Hg (II)] Complexes
In the present research, 4-aminoacetophenon reaction with benzoin in ethanol to procure compound [1]. Compound [1] was reacted with 4-aminobenzenesulfonamide and few drops from (glacial CH3COOH) in EtOH to yield compound [2]. Compound [2] reaction with 2-mercaptobenzoic acid or sodium azide or various anhydrides to give Thiazine [3], tetrazole [4] and 1,3- oxazepine derivatives [5,6] respectively. The structure of synthesized compounds identified by spectral data (FT-IR), (1H-NMR) spectra and analysis (CHN-S). The Schiff base ligand and synthesis some transition metals complexes [Co (II), Ni (II), Cu (II) and Hg (II) of this ligand were described via FTIR, UV-Visible Spectroscopy and the elemental analysis (CHN-S). in our coclusion we found The corrosion inhibition study of Thiazine [3] tetrazole [4] 1,3- oxazepine[5] ligand and their complexes on mild steel in (0.1M) hydrochloric acid were researched by weight loss
