Abstract:
The N,N′-bis(ferrocenylmethylene)ethylenediamine Schiff base was synthesized by condensing ferrocenylaldehyde with ethylenediamine. The complexes of the Schiff base with Zn(II), Co(II), Ni(II) and Fe(III) ions were synthesized. The compositions and properties of the ligand and its complexes were established by elemental analyses, IR, 1H NMR, UV-Vis. spectra and molar conductances.Keywords:

Abstract Schiff bases obtained by reaction between β-ketoester ethyl-α-ketocyclopentylcarboxylate (C8H12O3) and various aliphatic diamines NH2(CH2)nNH2, where n = 2, 3, 4, were prepared and studied. Also prepared was the complex of NiII and the Schiff base of 1,3-trimethylenediamine (L), with the formula NiLCl2-6H2O. The Schiff bases were characterized by elemental analysis, IR spectroscopy and 1H and 13C-NMR. The NiII compound was characterized by elemental analysis, IR, UV and visible spectroscopy, magnetic susceptibility and thermal analysis. A tetrahedral environment set N2Cl2 of donor atoms is proposed for NiII

Abstract Potassium tetrachloro(ethylenediamine)iridate(III) and cis-dichlorobis(ethylenediamine) iridium(III) chloride were obtained by the reaction of iridium(III) chloride and ethylenediamine in a weakly acid aqueous solution. The condition for the formation of each compound depends on the mole ratio of iridium to ethylenediamine and pH of the solution. Trans-dichlorobis(ethylenediamine)iridium(III)chloride was prepared from potassium tetrachloro(ethylenediamine)iridate(III) and ethylenediamine. The geometrical configurations of the two isomers were determined by infrared spectra, and checked by ultraviolet spectra.

Abstract The reaction of hexachloroacetone (HCA) with various diamines led either to the corresponding diamides or to cyclic ureas, depending on the molar ratio of the reactants. In the cases of ethylenediamine, 1,2‐diaminocyclohexane and o ‐phenylenediamine, the reaction with HCA also formed bisimidazole derivatives. These latter unexpected products were also formed when the diamine reacted with trichloroacetate esters or with carbon dioxide.

In this work, BSEA-SBA-15 was prepared for the first time, which was prepared by covalently anchoring Schiff-base compound (N,N´-bis(salicylidene)ethylenediamine (BSEA) on SBA-15 by hydrothermal method. The structure and physicochemical properties were determined by elemental analysis, XRD, nitrogen adsorption–desorption, thermogravimetric analysis and FTIR spectroscopy, SEM, BET surface area and BJH pore size. The average pore diameter after the modification is 69A. It is expected that BSEA-SBA-15 can be used as an effective adsorbent for the removal of metal ions due to having porous structure and active functional groups.
