Abstract:

Schiff's bases are one of the important classes of the ligands, which are obtained by the condensation of amine and aromatic aldehyde. The metal complexes of Schiff's bases are widely considered because they show excellent biological activities. Such as antimicrobial, antitumor, antibacterial, and anti-fungal properties. The present studies deal with synthesis and characterization of Schiff's base transition metal complexes synthesized from general formula (ML) M=Co(II) and Cu(II); L = Schiff's base ligand derived from hydroxy trizene and aromatic aldehyde. The Synthesized complexes were chara

Abstract:

Schiff's bases are condensation products of primary amines with carbonyl compounds. Schiff bases (imines) possess wide variety of biological activities that include antibacterial and antifungal activity. In present work, Schiff bases from 3,5- Dimethoxyphenol (aryloxy moiety) as starting material synthesized. Esterification of 3,5- Dimethoxyphenol led to formation of (3,5-Dimethoxy-phenoxy)-acetic acid ethyl ester (1). (3,5-Dimethoxy-phenoxy)-acetic acid hydrazide (2) is derived from Compound (1) by hydrazination. Compound (2) was reacted with different aromatic aldehydes to yield novel imines

Abstract:

There is a crucial medical need for the progress of new antibacterial agents with new and more efficient mechanisms. Schiff bases are stated to have a wide range of pharmacological activities, including antimicrobial, antibacterial, antifungal, antioxidant, and anticancer activities, which are largely due to the distinguishing C=N group. Furthermore, heterocyclic compounds containing acyclic hydroxylated side chains, for example, acyclovir (ACV), are an essential class of antiviral acyclonucleosides. Therefore, this work was to synthesize and evaluate a new series of acyclovir analogues bearin

Reaction of 8-aminoquinoline with pyridine-2-carboxaldehyde (2), pyridine-3-carboxaldehyde (3), pyridine-4-carboxaldehyde (4), and benzaldehyde (5) yields the corresponding aminals or Schiff's bases according to reaction conditions; analogous results are obtained from the reaction of 1-amino-naphtalene with pyridine-2-carboxaldehyde (6).

Abstract:

A hydrazone Schiff base has been synthesized by the interaction of ethanolic solutions of antiglyoxime hydrazine with 2-acetyl-5-methylfuran to obtain the Schiff base L′. The complexes of Co(II), Ni(II) and Cu(II) of this Schiff base was synthesized and studied. The Schiff base and its metal(II) complexes were characterized based on solubility, percentage yield, elemental analysis, melting point/decomposition temperatures, infra- red spectral (FT-IR), conductivity measurement, magnetic susceptibility and water of crystallisation. Based on the results the prepared Schiff base and synthesized co

Two new glycine-Schiff base copper(II) complexes were synthesized. Single crystal X-ray diffraction (SCXRD) allowed us to establish the structure of both complexes in the solid state. The glycine-Schiff base copper(II) complex derived from 2′-hydroxy-5′-nitroacetophenone showed a mononuclear hydrated structure, in which the Schiff base acted as a tridentate ligand, and the glycine-Schiff base copper(II) complex derived from 2′-hydroxy-5′-methylacetophenone showed a less common tetranuclear anhydrous metallocyclic structure, in which the Schiff base acted as a tetradentate ligand.

A Schiff base ligand, N 1 , N2 -bis[(4-methoxyphenyl) methylidene]-1,2-ethanediamine (SBL), was derived by the condensation of 4-methoxybenzaldehyde with ethylene diamine followed by complexation with divalent transition metals. The synthesized Schiff base ligand (SBL) and its complexes 1-5 were characterized on the basis of IR, 1H-NMR, 13C-NMR, MS spectral, molar conductance and elemental analyses data. The structure of Schiff base ligand (SBL) was also confirmed by single crystal x-ray crystallographic study. The conductivity data suggests non-electrolytic nature of these complexes. The comp
