A novel chelate-assisted C−C bond formation on a Cd(II) complex of an asymmetric heptadentate(N7) tripodal Schiff base ligand

Synthesis and Spectral Studies of Cr(III), Mn(II), Co(II), Ni(II), Cu(II) and Cd(II) Complexes with New Bidentate (N,O) Schiff Base Ligand bearing an Oxime functional group

“…The easily preparation route of this kind and its ability of forming metal complexes with different metal ions makes chemists very interesting in synthesis and characterization of Schiff bases and their complexes (3,4) . Schiff bases have different chelation behavior, where it able to coordinate with metal ions as momo- (5) , bi- (6) , tri- (3,4,7) , tetra- (8) , penta- (9) , hexa (10) -, and heptadentate (11) . Schiff bases complexes have various applications in catalytic field (12,13) .…”

Preparation, characterization and catalytic application of molybdenum Schiff‐base complex immobilized on silica‐coated Fe3O4 as a reusable catalyst for the synthesis of pyranopyrazole derivatives

“…A literature search reveals that we and others have explored different usages of magnetic Fe 3 O 4 nanoparticles as magnetically recoverable catalysts in organic reaction processes. Additionally, transition metal Schiff‐base complexes have attracted much interest in the field of catalysis because of the extensive variety of applicability, like chemical stability, controlling the performance of metals in a large diversity of valuable catalytic transformations and stabilization of different metals in various oxidation states . Immobilization of above compounds on the surface of solid supports and their applications as heterogeneous catalysts have received special attention.…”

Mn(III)–pentadentate Schiff base complex supported on multi‐walled carbon nanotubes as a green, mild and heterogeneous catalyst for the synthesis of tetrahydrobenzo[b]pyrans via tandem Knoevenagel–Michael cyclocondensation reaction

“…Increasing demand for eco‐friendly, green and mild methods using heterogeneous recyclable and reusable catalysts encouraged us to improve a safe alternative process for the synthesis of tetrahydrobenzo[ b ]pyrans via tandem Knoevenagel–Michael cyclocondensation reactions in the presence of a recyclable and reusable heterogeneous catalyst under solvent‐free conditions at room temperature. With this aim and following our studies on design and synthesis of Schiff base complexes, complex supported on MWCNTs and pyran derivatives, in the work reported here we decided to immobilize Mn(III)–pentadentate Schiff base complex on the surface of MWCNTs using (3‐chloropropyl)trimethoxysilane as a Si linker and spacer. The designed MWCNT@Si–H 2 azosaldien system could be a novel and simple approach for loading metals in a variety of coordination modes (Scheme ).…”
