Article
Full-text available
Pyrazoline and its derivatives have numerous prominent pharmacological effects. Focusing on its anti-viral property, we have designed and synthesized three novel pyrazoline derivatives (A1–A3) through one-pot three components and characterized them using different spectroscopic techniques (FT-IR, 1H NMR, 13C NMR, and UV). These compounds were evalu...
Article
Aims This article describes the controlled synthesis and characterization of azo oxazolone as multifunctional group in which contain Carbonyl, imine and carbon double bond carbon bond, and their ring opening to azo-benzamide derivative in fast reaction( 5 90%). Objective UV, IR, proton-NMR, C13-NMR, Elemental analysis and MS spectrometry all synth...

This Article deals with the stepwise synthesis and spectroscopic characterization of some new azo benzofuran derivatives, started fromthe diazotization of substituted aniline coupled with 2-hydroxy benzaldehyde. On reacting of the azo of 2-hydroxy benzaldehyde with p-bromo phenacyl bromide, the benzofuran (3a-g) are obtained. The structure of the n...

The title compound, C9H11NO2, was obtained as unexpected product from the reaction of (4-{2-benzyloxy-5-[(E)-(3-chloro-4-methylphenyl)diazenyl]benzylidene}-2-phenyloxazol-5(4H)-one) with 2-methoxyaniline in the presence of acetic acid as solvent. The amide group is not coplanar with the benzene ring, as shown by the C—N—C—O and C—N—C—C torsion angl...
Article
In this research paper, a stepwise chemical reaction was conducted to synthesize and develop of a new potent azo-oxazolone, which was used as prototypical molecule for production of two series of azo-benzimide (5a–j) and azo-imidazolone (6a–j). FT-IR, ¹H NMR, ¹³C NMR and CHN analysis were used for the structural elucidation. The high biological eff...

1,3,5-trisubstituted pyrazoline derivatives containing both azo-linkages and benzyloxy moieties have been synthesized via one-pot three-component condensation reaction in high yields and short reaction process. The structures of the synthesized compounds were characterized by using FT-IR, 1 H-NMR, 13 C-NMR and 13 C-DEPT 135 spectra.

Some new azo-imine dyes have been synthesized via the diazotization of sulphanilic acid and its coupling reaction with salicylaldehyde giving a starting material 4-((3-formyl-4-hydroxyphenyl)diazen yl)benzenesulfonic acid. The later reacted with different substituted anilines to give the target azo-imine dyes [4-((3-((4-substitutedphenylimino)methy...

p-Aminoacetophenone underwent diazotization and coupling reaction with 2-chlorophenol to give a starting material 4-(4-hydroxy-3-chlorophenyl)azoacetophenone. The prepared starting material was benzylated with benzylbromide producing 4-[4-benzyloxy-3-chloro-phenyl]azoacetophenone. The later has been reacted with different substituted benzaldehydes...
Article
Full-text available
3-(4-chlorophenylazo)-4-(4-chlorobenzyloxy)benzaldehyde was prepared and reacted with different prepared substituted azo-benzoloxy acetophenones giving some chalcones which then treated with hydrazine hydrate to give the target compounds 3,5-disubstituted pyrazoline compounds which contain two different azo-linkages and two benzyloxy moiteis. The s...
Article
Full-text available
The starting material azo‐benzyloxy acetophenone (2) has been synthesized in three steps; the direct diazotization of p‐aminoacetophenone and its coupling reaction with m‐cresol gave azo‐acetophenone (1), which was benzylated with p‐chlorobenzylchloride to give the starting material (2). The later compound was subjected to the one‐pot three‐compone...

A series of new substituted azo-pyrazolinecompounds have been synthesized and evaluated for their in vitro antimicrobial activity along with standard ciprofloxacin against gram positive Staphylococcus aureus and gram negative Klebsiellapneumoniae. The preparation of the newly azo-pyrazolinecompounds have been started by the direct diazotization of...

Azo dyes 3-(4-chlorophenylazo)-4-hydroxyacetophenone (L) were synthesized by reaction of p-chloroaniline to p-hydroxyacetophenone through mono azo-coupling reaction. Reaction of new azo-dye with La(III), Ce(III), Sm(III), Eu(III) and Dy(III) salts gave mono nuclear complexes, the complexes exhibited 1:3 M:L stoichiometry. Complexes showed octahedra...
