Ni(Salen) complexes as an efficient, homogeneous catalysts revealed a catalytic activity toward the one-pot synthesis of tetrahydropyridine derivatives through the pseudo five-component reactions of aromatic aldehydes, aromatic amines, and β-ketoesters in ethanol at room temperature. Mild reaction conditions, good yields, high diastereoseletivity, operational simplicity, and the absence of tedious separation procedures, clean reaction profiles, high atom economy, inexpensive starting materials, and environmentally benign catalyst are the key advantages of the present MCRs protocol.

A new 4,4′-bipyridine (4,4′-byp) mediated 1D- polymeric FeIII complex (complex 1) of Schiff base ligand H2L, a 1:2 condensation product of 1,2-diaminopropane and salicylaldehyde, has been synthesized. Complex 1 is structurally characterized by single crystal X-ray diffraction. A phenoxo bridged dinuclear FeIII complex (complex 2) of analogous ligand has been synthesized also. Dioxygen activation in terms of Phenoxazinone synthase activity using o-aminophenol (OAPH) as a model substrate catalyzed by both the complexes are thoroughly investigated here. ESI-MS spectral study reveals that polynuclear complex 1 dissociates into mononuclear units while dissolve in methanol during catalytic study. The kinetic study illustrates that both the complexes have well competence towards o-aminophenol oxidation where dinuclear FeIII species demonstrate higher activity than mononuclear intermediate species. Important finding from the mass spectral and electrochemical study provide significant information of the mechanistic pathway of the functioning phenoxazinone synthase like activity of synthesized iron complexes.

A new Cu-Zn heteronuclear complex, [CuZnCl2L], where L is the dianionic form of N,N-bis(salicylidene)propane-1,2-diamine, has been prepared and characterized by elemental analyses, IR, and single-crystal X-ray crystallographic determination. The crystal of the complex is monoclinic: space group P21/c, a = 12.195(5), b = 8.009(3), c = 18.082(7) A, β = 93.745(6)°, V = 1762.3(12) A3, Z = 4. The Cu atom is coordinated by two phenolate O and two imine N atoms of the Schiff base ligand, forming a square planar geometry. The Zn atom is coordinated by two phenolate O atoms of the Schiff base ligand and two Cl atoms, forming a tetrahedral geometry. The effect of the Schiff base ligand and the complex on the antimicrobial activity against Staphylococcus aureus, Escherichia coli, and Candida albicans was studied.
