Two new symmetrical Schiff bases have been prepared by the condensation of ethylenediamine and two benzaldehyde derivatives, 2-hydroxybenzaldehyde and 2,4-dimethoxybenzaldehyde. The electronic transitions within these Schiff bases molecules in chloroform solvent have been investigated by UV-Vis spectroscopy. The 1H NMR and IR spectra were studied and assigned to related groups. Furthermore,...

The reactions of 1 - chloro - 2 - nitro benzene with 2 - Amino thio phenol yield the 2 - ( ( nitro phenyl ) thio ) aniline and then 2 , 2' - thio dianiline of this compound was prepared . Also the symmetrical potentially pentadentate N 2 O 2 S Schiff base ligand 2 , 2' - ( ( ( thio bis (1 , 2 - phenylene ) ) bis ( azanilidene ) ) bis ( methenilidene ) ) diphenol ( H 2 L ) obtain by added salicy...

Accepted on 25 th August 2014 _____________________________________________________________________________ ABSTRACT Synthesis of symmetrical Schiff bases (1-4) employed by using condensation methods. Purity was monitored by TLC and column chromatographic techniques. In this present study cyclic voltammetric behavior of symmetrical Schiff bases (1-4) were studied. The cyclic voltammetric studie...

Many Organothallium Compounds have been used in medicine, industry and antibacterial activity. Optical properties are among the most fascinating and useful properties of many complexes and have been extensively studied using a variety of optical spectroscopic techniques. A basic understanding of the optical properties and related spectroscopic techniques is essential for characterization about ...

the vo(iv) complexes of tridentate ono schiff base ligands derived from 2- aminobenzoicacid and salicylaldehyde derivatives were synthesized and characterized by ir, uv–vis and elemental analysis. electrochemical properties of the vanadyl complexes were investigated by cyclic voltammetry. a good linear correlation was observed between the oxidation potentials and the electron-withdrawing charac...
