تم في هذا العمل دراسة السلوك الكهركيميائي لبارا نترو الأنيلين و ميتوكسي البنزألدهيد باستخدام الطريقة الفولتومترية الحلقية على مسرى الغرافيت الزجاجي في وسط قلوي. تبين أن بارانترو الأنيلين احتاج إلى خمس الكترونات ليتم إرجاعه.
In this work the electrochemical behavior of Para-nitro aniline and metoxy benzealdehyde was studied by cyclic voltammetric method on glassy carbon electrode in alkaline medium . It was found that the Para- nitro aniline needed five electrons to reduce to the azo group.

Quinaldine includes shifting hydrogenes which might be involved in
important reactions as the condensation and Mannich reactions.
Quinophtalone has been prepared through the reaction of quinaldine with
phtalyic anhydride in the presence of alumini
um chloride anhydrous
Imines derivatives have been prepared through the reaction of
Quinophtalone with hydroxideamine and phenyl hydrazine and then
diazotion anyhydride has been done to the resulting compounds.
The prepared compounds were characterized by ( H1NMR,IR, MS)
A novel Azo-Schiff base ligand L 2-[1.5-Dimethyl-3-[2-(5-methyl-1H-indol-
3-yl) - ethylimino] - 2 - phenyl - 2,3 - dihydro - 1H - pyrazol - 4 - ylazo] - 5-
hydroxy -benzoic acid has been synthesized from reaction 1.5-Dimethyl-3-[2-(5-
methyl- 1H -
indol - 3 - yl) - ethylimino] - 2 - phenyl - 2.3 - dihydro - 1H -
pyrazol - 4 - ylamine (A) with m-hydroxy benzoic acid. Then, its Zn(II), Cd(II)
and Hg(II) complexes were synthesized with the general formula [ML1Cl]
where M = Zn(II), Cd(II) and Hg(II) are reported. The ligand and its metal
complexes have been characterized by elemental analysis, metal content,
Chloride containing, molar conductance, FT-IR, 1H and 13C- NMR, UV-Vis
spectra, magnetic susceptibility, thermal analysis, and mass spectra. The
activation thermodynamic parameters, such as ΔE*, ΔH*, ΔS* ΔG* and K are
calculated from the TGA curve using Coats-Red fern method. The all prepared
complexes were assayed for antibacterial (Escherichia coli and Staphylococcus
aureus) activities by disc diffusion method. The results indicate that all tested
ligand and complexes show antibacterial activity against E. coli and S aureus,
as gram negative and positive bacteria.
In this research two Indomethacin derivatives were
synthesized, Indomethacin ethyl ester was synthesized by
The Direct Esterification method by reacting indomethacin
with ethanol within different conditions of time, molar
ratios and solvents in a
cidic medium using homogeneous
acid catalysts such as sulfuric acid and methane sulfuric
acid and heterogeneous acid catalysts such as amberlyst-
15. Then indomethacin acid hydrazide was synthesized by
condensing the previous ester with hydrazine hydrate and
the best conditions were studied of time, molar ratios,
solvents and different temperatures without using any
catalyst.
macrocyclic hydrazone Schiff base was synthesized by reaction of
succinicdihydrazide, Adipicdihydrazide with acetylacetone, adipicdihydrazide
with terephtaldialdehide and sebacicdihydrazide with terephtaldialdehide.
We have synthesized some new compounds from 2-Acetyl Fluorene\ Thiophene
2-carbaldehyde chalcone via condensation and cyclization reactions between the chalcone and each of thiourea and urea, hydroxylamine hydrochloride and hydrazine hydrate, these
reactions afford these compounds:
3-(2-fluorenyl)-5-(2-thienyl) pyrazoline(4), 3-(2-fluorenyl)-5-(2-thienyl) Isoxazoline(3), 4-(2-fluorenyl)-6-(2-thienyl) pyrimidinone-2 (2) and 4-(2-fluorenyl)-6-(2-thienyl) pyrimidine-2 tione (1). Also 3-(2-fluorenyl)-5-(2-thienyl) isoxazole (5), were prepared via bromination of chalcon and cyclization the later with hydroxylamine hydrochloride.
Identification and determination of compounds structurs were carried out by (IR,
1H-NMR, 13C-NMR, LC-MS) spectrum Analysis.
