High Selectivity on The epoxidation of Cyclooctene Catalyzed by Tri-and Tetra-Dentate Imine Vanadyl Chelates Using H2O2
High yield of VO(II) chelates incorporating new imine ligands were obtained by the condensation reaction between 2-hydroxynaphthaldehyde or 3-ethoxysalicylaldehyde and o-phenylenediamine s in 1:1 molar ratio. All the complexes are non– hygroscopic in nature and stable to the atmosphere. The synthesized ligands and the isolated imine chelates have been characterized various physico-chemical techniques. The results obtained from these studies and ... إقراء المزيد

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. ... إقراء المزيد
