Study on Schiff Bases
Derived from Sulfathiazole and Sulfamethoxypyridazine.
The level of primary products naturally decreases, while the level of triene conjugates and Schiff bases
increases uniformly when passing from [N.
In view of the wide applications of Schiff bases
in the drug design, a facile one pot synthesis (Fareed et al.
In a previous work we have reported the synthesis of a series of bis Schiff bases
of isatin , for this study the 3-(2-(2-hydroxy-3-methoxybenzylidene)hydra- zono)indolin-2-one" bis Schiff base
has been selected in an attempt to synthesize metal complexes and study the impact of coordination on the overall biological activity of the ligand molecule.
There is a continuing interest in transition metal complexes of Schiff bases
because of the presence of both nitrogen and oxygen donor atoms in the backbones of these ligands, some of these complexes have been exhibit interesting physical and chemical properties and potentially useful biological activities .
Abstract Schiff base
epoxy resin was used as a component of self-stratifying compositions, in which different acrylic resins were used.
abbreviated as DHB-3-MAP, DHB-4-MAP, and DHB-6-MAP were synthesized by the condensation reactions of 2,4-dihydroxy benzaldehyde (DHB) with amino-methyl pyridines (2-amino-3-methylpyridine, 2-amino-4-methylpyridine, and 2-amino-6-methylpyridine), respectively .
The general mechanism for the formation of the Schiff base
shown in Scheme 2:
Abstract Metal-containing epoxy resins [Er-M(II)] have been prepared by the reaction of Schiff base
metal complexes and epichlorohydrin in basic medium.
4) shows that oA, mA and pA Schiff base
products have a maximum absorption at 488, 480 and 535 nm versus their corresponding blank respectively, where as the reagent blank has a maximum absorption at 360 nm versus distilled water.
The Schiff bases
and their metal complexes have a wide range of applications [1-3].
