Department of Biochemistry and Chemistry, Punjab Agricultural University, Ludhiana-141 004, Punjab, India <em>Manuscript received 26 October 2005, revised 1 August 2007, accepted 26 November 2007</em> Condensation of 4-bromoaniline with benzaldehyde and substituted benzaldehydes (1-8) in equimolar ratio resulted in the formation of benzal-4-bromoaniline and its C-phenyl derivatives (la-8a). Addition of thioglycolic acid to la-8a yielded the respective 4-thiazolidinone (lb-8b). The synthesized compounds were characterized on the basis of elemental analysis and spectral studies and were screened

In the crystal, molecules related by translation in [001] interact through short intermolecular Br...F contacts [3.276 (2) and 3.284 (2) Å], thus forming two types of crystallographically independent chains.

Abstract:

Alkylation of 2-bromoaniline with benzyl bromide under ostensibly basic N-alkylation conditions resulted in migration of bromine from the 2- to the 4-aryl position. Herein we report our studies to elucidate the mechanism of this rearrangement with the objective of suppressing this unexpected outcome. We find that careful choice of reagents is critical, and that this behavior may be extrapolated to alkylation reactions of electron-rich bromo- and iodoanilines in general.

Abstract:

A simple and sensitive spectrophotometric technique was developed for the determination of carbofuran in its formulations, water and grain samples. The method was based on the alkaline hydrolyzed product of carbofuran phenol interacted with diazonium salt of 4,4-azo-bis-3,3′5,5′-tetra bromo aniline. The maximum absorbance of the red coloured derivative was measured at 470 nm. The beer’s law was obeyed in the concentration range of 0.1-16.0 µg/mL. The interference of the non target species were studied on the determination of carbofuran which increases the selectivity of the method. The present

Abstract:

In the present paper, synthesis of few novel pregnane derivatives and their evaluation as potential anti-hyperlipidemic and anti-oxidant agents has been reported. The synthesis of 3&#946;-hydroxy- 16&#945;-methoxy pregn-5-en-20-one (4) was achieved by reaction of 3&#946;-hydroxy-5,16-pregnadiene-20-one (3) with KOH/MeOH under reflux. Compound 4 on treatment with succinic and phthalic anhydride afforded compound 6 and 7, respectively. The reaction of the C-20-oxime-pregnadiene (8) with 1,5- dibromohexane yielded 20-(O-6-bromo hexyl)-oximino-3&#946;-hydroxy-pregn-5, 16-diene (9).

AbstractIn this article, we report the synthesis and characterization of silver dispersed poly(m-toluidine-co-2-bromoaniline) copolymer synthesized by chemical oxidative polymerization method. The synthesized copolymer composites were subjected to different analytical characterization methods, such as FT-IR, UV, XRD, SEM, photoluminescence and electrical conductivity studies. All the polymer samples are found to be soluble in common organic solvents. UV absorption spectra show a red shift when silver nanoparticles are dispersed in the copolymer.

Abstract:

`Bridge-flipped' isomers may be defined as pairs of molecules related by a reversal of a bridge of atoms connecting two major parts of the individual molecules. This kind of isomerism is commonly found among benzylideneanilines and phenylhydrazones. Isostructural pairs might be suitable for co-crystallization and are thus useful in the preparation of new solid materials. Although most of the examples of bridge-flipped isomeric benzylideneanilines and phenylhydrazones in the crystallographic literature are not isostructural, a small number of isostructural pairs have been reported by previous w
