Synthesis and characterization of nickel complexes derived from Schiff-Bases

Abstract

Aromatic Schiff-Bases constitute a large class of organic compounds containing the imine group (C=N) [1-3]. 2-hydroxybenzaldehyde (salicylaldehyde) which has been frequently used for the synthesis of aromatic Schiff-Bases, it has many biological applications, such as analgesics, anti-inflammatory, antibacterial, antiviral and bactericidal activities [4-6]. From above, this project proposed the synthesis of three Schiff bases derived from salicylaldehyde prepared by condensation between salicylaldehyde with different p-substituted anilines (H, NO2 and MeO). Schiff-Bases synthesized were used as starting compound for the synthesis of nickel complexes. The synthesis of nickel complexes were carried out by adding of alcoholic solution of ligands (2 eq.) in aqueous solution of NiCl2.6 H2O (1 eq.) contain KOH (1eq.) 3 hours. After thisMatsumoto et al. time, the reaction was kept to r.t. to obtain a precipitates. The precipitates were filtered under vacuum and they were characterized by GC-MS, FT-IR and UV-Vis
