Synthesis and characterization of vanadyl(IV) complexes of Schiff bases derived from anthranilic acid and salicylaldehyde (or its derivatives) or acetylacetone. Single crystal X-ray structures of the oxidized products

Synthesis, spectral characterization, electrochemistry and catalytic activities of Cu(II) complexes of bifunctional tridentate Schiff bases containing ONO donors

“…[8,9] All the reagents used were chemically pure and of analytical reagent grade. Solvents were purified and dried according to standard procedures.…”

“…In copper (II) complexes the metal ions have either a four or six coordination geometry and there only a few exceptions to this. The 3d 9 configuration of Cu(II) is of particular interest because it represents a simple one magnetic hole system. [7] In view of the rich photophysical and catalytic properties of organometallic copper(II) complexes, the introduction of Schiff bases with an O-N-O donor set to Cu(II) complexes containing triphenylphosphine has been carried out.…”

Catalytic oxidation and C–C coupling reactions of new ruthenium(III) Schiff base complexes containing PPh3 or AsPh3 co-ligands

“…Cyclic voltammetric studies were carried out in acetonitrile using a glassy-carbon working electrode and potentials were referenced to standard calomel electrode. Powder XRD were recorded using a [17] and aryl-aryl coupling reactions [18] were carried out by using reported literature methods.…”

Complexos de vanádio como miméticos de peroxidases e catalisadores de oxidação: síntese e caracterização espectroscópica

“…Compostos de vanádio(IV) e (V) com Iigantes contendo grupos e carboxilatos e imínicos, têm sido muito estudado nos últimos anos [31,32,33,34,35] …”

“…Este novo complexo também foi sintetizado segundo metodologia já estabelecida [32], com algumas modificações. Dissolveu-se Hdbhbal (2,5 mmol, 0,608 g) em 20 mL de CH3CN, à temperatura de 35-40°C, e adicionou-se, lentamente, gota a gota,…”
