Catalytic potential of new mononuclear Cr(III)-Schiff base complexes for selective oxidation of benzyl alcohol by H2O2
IN THE PRESENT CONTRIBUTION, SOME NOVEL CR(III) COMPLEXES WERE SYNTHESIZED FROM TRI- AND TETRA-DENTATE IMINE LIGANDS DERIVED FROM 3-ETHOXYSALICYLALDEHYDE OR 2-HYDROXYNAPHTHALDEHYDE WITH 2-AMINOPHENOL OR _O_-PHENYLENEDIAMINE. ALL THE PREPARED LIGANDS WERE AUTHENTICATED BY IR, 1H, 13C NMR SPECTRA AND CHN ANALYSIS. INTERACTION OF THE SYNTHESIZED LIGANDS WITH CHROMIUM NITRATE PRODUCED THREE NOVEL CR(III) COMPLEXES. THE STRUCTURE OF THE PREPARED CR(III) COMPLEXES ... Read more

Synthesis, catalysis, antimicrobial activity and DNA interactions of new Cu(II)-Schiff base complexes
Structural features and catalytic activities of five ternary copper (II)-Schiff base complexes are investigated. The ligands are derived from 3–methoxysalicylaldehyde (MS) or 4– diethylaminosalicylaldehyde (DS) and amino acids {L-phenylalanine (Phe), L histidine (His) or DL-tryptophan (Trp)}, as primary ligands, and 2,4’-bipyridyl (DP) as secondary ligand. Cu(II)- complexes are characterized by various physicochemical tools. The catalytic efficiency of Cu(II)-complexes is studied ... Read more

Catalytic Oxidation of Benzyl Alcohol using Nanosized Ni/Cu  Schiff-Base Complexes and their Metal Oxides Nanoparticles
Three novel nanosized Cu and Ni Schiff-base complexes (ahpvCu, ahpnbCu, and ahpvNi) incorporating imine ligands derived from the condensation of 2-amino-3-hydroxypyridine with either 3-methoxysalicylaldehyde or 4-nitrobenzaldehyde were synthesized by a sonochemical approach. The structure of the ligands and their complexes was confirmed by IR, NMR spectroscopy, electronic spectra, elemental analysis, TGA, molar conductivity, and magnetic moment analyses. The results revealed ... Read more

Some New Nano-sized Mononuclear Cu(II) Schiff Base Complexes: Design, Characterization, Molecular Modeling and Catalytic Potentials in Benzyl Alcohol Oxidation
In the present contribution, some novel Cu(II) complexes were synthesized from tri- and tetradentate imine ligands. All the prepared compounds were elucidated by different physicochemical methods. Density Functional Theory calculations were carried out to explain the equilibrium geometry of the bsisnph and npisnph ligands and their Cu(II) complexes. Interaction of the synthesized ligands with Cu(II) affords nano-sized particles via TEM. ... Read more
