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 .
