Synthesis and Characterization of Chiral Nitrobenzaldehyde - Schiff Base Ligands [PDF]

Molecules, 2003
Three chiral nitrobenzaldehyde/Schiff base ligands (2a-c) were prepared by the reaction of ortho, meta, and para-NO2 substituted benzaldehydes (1a-c) with (1R,2R)-(-)-1,2-diaminocyclohexane. The structures of ligands 2a-c were characterized by IR, 1H-NMR, 13C-NMR and elemental analysis.

Structural characterization, luminescence and electrochemical properties of the Schiff base ligands

Journal of Luminescence, 2012
Abstract In this study, we prepared two Schiff base ligands N-(4-hydroxy phenyl)-2,4-di-methoxy benzaldimine (TS1) and N-(4-hydroxy phenyl)-2,5-di-methoxybenzaldimine (TS2) which were characterized by structural, spectroscopic and analytical methods. The ligands TS1 and TS2 were obtained as single crystals from ethanol solution.

Design, synthesis and analysis of Schiff based derivatives of Sulfadoxine drug and their metal complexes

Results in Chemistry
Sulfa drugs are the substituted pyrimidines containing anti-infective agents. The two novel Schiff base (SB) ligands were designed using sulfadoxine (Schiff base-1 (SB-1) ligand) and (Schiff base-2 (SB-2) ligand), computed, synthesized, and characterized.
