Abstract

In this study a new
Schiff base ligand was synthesized by the reaction of salicylaldehyde,
1,2-bis(bromomethyl)benzene and 4-nitrobenzenamine. [Cr(L)Cl₂]Cl·H₂O,
[Fe(L)Cl₂]Cl·2H₂Oand [Ru(L)Cl₂]Cl complexes were synthesized with this ligand and Cr(III), Fe(III) and
Ru(III) chloride salts. The structures of the ligand and the obtained
complexes were characterized using Elemental Analysis, FT-IR, ¹H-NMR,
¹³C-NMR, UV-Vis, Magnetic Susceptibility and Thermogravimetric Analysis.
The synthesized phenoxy-imine ligand is a ligand of the O₂N₂
type. The resulting metal complexes are mononuclear and have octahedral
geometry. Preliminary studies have also been carried out on the catalytic
effects of complexes in cycloalkane oxidation and in cycloalkene epoxidation.
In the general sense, the catalyst that triggers the highest product formation
in the synthesized catalysts are the Ru(III) complex. It is suggested that
Ru(III) complexes can be used in such catalysis reactions since they exhibit a
high catalytic effect on cyclohexane oxidation.
