cis-polybutadiene was functionalized using in–situ generated dmd as oxidant and tetra-n-butyl ammonium bromide as phase transfer catalyst (ptc). the epoxidation process was investigated by 1hnmr spectroscopy. 1hnmr spectrum analysis of products confirms the absence of ring opening side products in epoxidation reaction. various factors such as reaction temperature, reaction time and the concentr...

The anti-cancer Nano drugs Cisplatin, Carboplatin, Nedaplatin, Oxaliplatin, Heptaplatin and Lobaplatin were characterized by 1HNMR, 13CNMR, 31PNMR, Attenuated Total Reflectance Fourier Transform Infrared (ATR-FTIR), FT-Raman, HR Mass and UV-Vis spectroscopies and also by Scanning Electron Microscope (SEM), Transmission Electron Microscope (TEM), Differential Thermal Analysis-Thermal Gravim Anal...

Objective: Synthesis and evaluation of anti-inflammatory activity of some novel 7-azaisatin derivatives. Methods: Novel Schiff bases of 7-azaisatin (VI) were synthesized by condensation of ethyl-2-(1-benzyl-2-oxo-1,2-dihydro-3H-pyrrolo[2,3b]pyridin-3-ylidene) hydrazine carboxylate (V) with various primary amines. The compound (V) was synthesized by reacting ethylchloroformate with 1-benzyl7azai...

New coordination complexes of Co, Ni and Zn with Schiff base N’-((2-thioxo-1,2-dihydroquinoline-3yl)methylene) pyridine-4-carbohydrazide have been synthesized and characterized by several techniques using elemental analysis (C, H, N), IR spectra and 1HNMR spectra. The new Schiff base has been synthesized by the reaction of pyridine-4-carbohydrazide and 2-thioxo-1,2dihydroquinoline-3-carbaldehyd...

In this paper, two of the new antipyrine heterocyclic derivatives have been synthesized via formation Schiff bases. The bases compounds were generated from reaction 4-Ameno-antipyrine (4-AAP) with 3- hydroxybenzaldehyde and 4- nitrobenzaldehyde, which was converted to imidazolidinone by glycine. reactions monitored Thin Layer Chromatography (TLC). structure prepared confirmed physical available...

Synthesis of 2-(4-Acetyl-phenyl)-4-nitro-isoindole-1, 3-dione chalcones were performed by fusion 3-nitro phthalic anhydride with p-aminoacetophenone. Then the later was grinded different aromatic aldehydes in presence sodium hydroxide to produce new derivatives A3-10 without using any solvent formation N-arylphthailimide confirmed FTIR,1HNMR, 13CNMR spectroscopy and all final compounds tested f...

copper (ii) phthalocyanine and 2,9,16,23 tetrakis nitro copper (ii) phthalocyaninehas been synthesized respectively from phthalonitrile and 4-nitro phthalonitrile under solvent-free condition using two different catalystsovernanodimensionalzeolites. 4-nitro phthalonitrile synthesized from phthalimide in three steps. the newly prepared compounds have been characterized by ir, uv-vis, 1hnmr and m...
