“…The model compound for tetrazoles used was 5-phenyl-1H-tetrazole. Neshat et al (2023) [106] reported the synthesis and characterization of a Cu(II) complex CuL 2 (45) with a bidentate SB derived from Ortho-vanillin. The catalytic activity was studied in the oxidation of selected primary and secondary alcohols.…”

Complexes of Schiff bases (SBs) with metals are promising compounds exhibiting a broad range of applications, such as catalysts, polymers, dyes, and several biological activities, including antimicrobial, anticancer, antioxidant, antimalarial, analgesic, antiviral, antipyretic, and antidiabetic actions. Considering the crisis that the whole world is now facing against antimicrobial-resistant bacteria, in the present review, we chose to focus on the activity of SBs as antimicrobials, particularly underlying the most recent studies in this field. Finally, some interesting catalytic applications recently described for metal complexes with SBs have also been discussed.

“…Copper(II) Schiff base complexes have been studied for their catalytic properties, being efficient catalysts for oxidation reactions and gaining considerable attention due to their properties. Copper-Schiff base complex catalysts offer advantages in terms of high catalytic activity, versatility and selectivity, as well as simple work-up procedures and low copper content [25]. Their activity can be tuned by changes in ligand types and ligand coordination sites.…”

A new mononuclear Cu(II) complex [Cu(L2)(H2O)2], where L is the Schiff base 2-[2-(3-bromopropoxy)benzylideneamino] benzoic acid, was synthesized and covalently anchored onto an amino-functionalized SBA-15 mesoporous silica in order to obtain an efficient heterogeneous catalyst. The elemental, structural, textural and morphological characterization confirmed the coordination of the central Cu(II) ion with two ligands and two H2O molecules in the synthesized complex and its successful immobilization into the inner pore surface of the NH2-functionalized support without the loss of the mesoporous structure. The catalytic activity of the free or immobilized Cu(II) complex was tested in the oxidation of cyclohexene with H2O2 under an air atmosphere and the dismutation reaction of the superoxide radical anions with very good results. In addition, catalyst reuse tests claim its suitability in alkene oxidation processes or as a biomimetic catalyst.

Two bimetallic Fe(II)‐Cu(I) complexes, with tetrahedral Cu(I) center stabilized in a S2P2 environment, were synthesized and fully characterized using single crystal X‐ray diffraction, multinuclear NMR, IR and UV‐Visible spectroscopy techniques. Density functional theory with PBE0‐D3(BJ) functional was employed to elucidate the electronic features of these novel metal complexes. The computational analysis revealed that while all Cu(I) complexes adopted a tetrahedral geometry in the gas phase with shorter P−Cu(I) bonds than the S−Cu(I) bonds. These cationic complexes were highly active in the catalytic cycloaddition reaction of azides onto terminal alkynes. The CuAAC reaction were carried out at room temperature with as low as 1 mg (0.1 mol %) of catalyst loading to deliver high yields of the corresponding 1,4 adducts of 1,2,3‐triazoles in water under aerobic conditions.
