Carbon steel pipelines corrosion inhibition by some novel imines during acidizing treatment of oil wells: Electrochemical and quantum chemical studies
The corrosion protection of the equipments and vessels is one of chief concerns of the maintenance and design engineers. From this point of view, three novel imine compounds were prepared and their structures were characterized by X-ray, 13C-NMR, 1H-NMR, mass, UV-Vis, FT-IR, spectral data and elemental analyses. The corrosion inhibition of the investigated inhibitors towards carbon steel in 15% HCl ... Read more

Design,  Synthesis, Structure Inspection,  Biological Screening,  and DNA Binding Study of  Some New VO(II), Pd (II) and Ag(I)  Chelates incorporating Tri-dentate Chemo Sensor Imine Ligand
The present study was conducted to synthesis of some new imine VO(II), Pd(II) and Ag(I) complexes derived from 2-[(2-Hydroxy-naphthalen-1-ylmethylene)-amino]-benzoic acid were synthesized. The prepared imine ligands were analyzed by their melting point, IR, 1H NMR and 13C NMR spectroscopy. The investigated imine complexes were characterized by elemental analysis, FT IR, Uv-vis and thermal analysis (TGA) in air from ambient temperature ... Read more

Development, structural investigation, DNA binding, antimicrobial screening and anticancer activities of two novel quari-dentate VO(II) and Mn (II) mononuclear complexes
Two novel VO(II) and Mn(II) imine chelates derived from the condensation of o-phenylenediamine (PN) with 3-ethoxysalicylaldehyde(ES) were synthesized. The prepared ESPN imine ligand and its chelates were investigated _via_ different analytical and physicochemical tools. Correlation between all the obtained results, the parent ligand behaves as tetra-dentate ONNO ligand and coordinates to Mn(II) and VO(II), in octahedral and square pyramidal geometry, ... Read more

Synthesis, theoretical investigations, biocidal screening, DNA binding, in vitro cytotoxicity and molecular docking of novel Cu (II), Pd (II) and Ag (I) complexes
Three new Cu(II), Pd(II) and Ag(I) complexes with bi-dentate Schiff base ligand "HL" namely 2-[(4-Chloro-benzylidene)-amino]-phenol were synthesized. The stoichiometric ratios and physicochemical properties of these complexes were determined using elemental analyses (C, H, and N), magnetic measurements, IR, UV-Vis spectra, molar conductivity and thermal analyses. The results revealed that the metal ions coordinated with ligand HL through azomethine nitrogen and ... Read more

Sonochemical synthesis, structural inspection and semiconductor behavior of three new nano sized Cu(II), Co(II) and Ni(II) chelates
Three novel nanosized Cu(II), Co(II) and Ni(II) complexes of imine ligand attained from the condensation of 2‐amino‐3‐hydroxypyridine and 3‐methoxysalicylaldehyde have been prepared and investigated using diverse chemical methods such as NMR, CHN analysis, conductance, IR, Spectral studies, TGA and magnetic moment measurements. The obtained data confirmed that the synthesized complexes have metal: ligand ratio of 1:1 and octahedral geometry for ... Read more

DNA interaction, antimicrobial, anticancer activities and molecular docking study of some new VO(II), Cr(III), Mn(II) and Ni(II) mononuclear chelates encompassing quaridentate imine ligand
The present study was conducted to synthesis of some new imine Cr(III), VO(II), Mn(II) and Ni(II) complexes derived from the condensation of 2-amino phenol with 2-hydroxynapthaldehyde were synthesized. The prepared HNPN imine ligand was analyzed by its melting point, IR, 1H NMR and 13C NMR spectroscopies. The investigated HNPN imine complexes were characterized by elemental analysis, FT IR, UV–vis and ... Read more
