Schiff bases are versatile ligands and known to be synthesized from the condensation of an amino compound with carbonyl compounds. These compounds along with their metal complexes are considered to be an important as catalysts in various biological processes. Also Schiff base complexes are gaining popularity among the various industries including polymers, dyes and pharmaceutical. This review s...

This paper presents a simple method that reduces the problem of detecting conflictfree assumption-based knowledge bases to the problem of testing satisfiability.

Three new Schiff bases derived from the condensation reaction of thiophene-2-carbaldehyde and DL-alanine, DL-valine and DL-phenylalanine have been synthesized and their Co(II), Ni(II) and Cu(II) complexes have been prepared. The Schiff bases and the complexes have been characterized by their analytical and spectral data. The protonation constants of the Schiff bases and stability constants of t...

Acylhydrazine derived furanyl and thienyl Schiff bases and their Cu(II) complexes have been prepared and characterized on the basis of their physical, spectral and analytical data. The preferred enolic form of the Schiff base function as a tetradentate ligand during coordination to the metal ion yielding a square planar complex. The Schiff bases and their complexes with different anions were te...

Biologically active tridentate amino acid (Alanine, Glycine & Tyrosine) derived Schiff-bases and their Co(II), Cu(II) & Ni(II) complexes have been synthesised and characterised on the basis of their conductance and magnetic measurements, elemental analysis and (13)C-NMR, (1)H-NMR, IR and electronic spectral data. These Schiff-bases and their complexes have been evaluated for their antibacterial...

It is well known that a lot of organic polymers of liquid crystals containing azo-groups exhibit optical anisotropy after polarized UV light irradiation. In recent year, optical properties of anisotropic nanoparticles in polymers of non-crystalline solid being regularly aligned by external mechanical or magnetic stimulus have been studied with polarized fluorescence spectroscopy and Bragg refle...

The two independent mol-ecules in the asymmetric unit of the title Schiff base, C(22)H(24)N(2), lie across centers of inversion. The C=N double bonds are in a trans configuration.

The title compound, C(16)H(16)ClNO(3), is a Schiff base displaying a trans configuration of the C=N double bond. In the crystal structure, inter-molecular C-H⋯N and bifurcated C-H⋯(O,O) hydrogen bonds are observed.
