Study of Super Capacitive Behavior of Polyaniline/manganese Oxide-Carbon Black Nanocomposites Based Electrodes

The supercapacitive behavior of polyaniline/MnO2-carbon black (PANI/MnO2-CB), MnO2-CB nanocompositesand CB was studied. MnO2-CB made by the in situ direct coating method to deposit MnO2 onto CB; then PANI coating was coated on it. Morphology of the nanocomposite was studied by X-ray diffraction (XRD), Fourier transform...

Electrochemical Behaviour of Nifedipine and Nitrendipine in Chloroform and Chloroform-Isopropanol Mixture

The electrochemical behavior of nifedipine (I), nitrendipine(II) and their photodegradation products has been studied by employing electrochemical techniques in chloroform and in 1:4 mixture of chloroform-isopropanol using piperidinium perchlorate (PPC) as supporting electrolyte. It has been shown that I and II undergo in a 4e, 4H+ irreversible reduction reaction, while the reduc...

Microwave-assisted preparation of Nـ alkyl 2ـ ketomethyl quinolines on Solvent-free Conditions

Cycloaddition of Diphenylnitrilimine to 1,5-Benzodiazepines

The cycloaddition reaction of diphenylnitrilimine on the 1,5-benzodiazepines has been studied. New molecules of triazolobenzodiazepines type have been isolated and characterized.

Ultrasound based method for one-pot synthesis of substituted imidazoles using SiO2-OSbCl2 as highly effective and reusable catalyst

A simple highly versatile and efficient sonochemical synthesis of 1,2,4,5-tetrasubstituted and 2,4,5-trisubstituted imidazoles is achieved by condensation of 1,2-dicarbonyl compound, aldehyde, ammonium acetate and primary amine using antimony trichloride immobilized on silica gel (SiO2-OSbCl2) as a catalyst in ethanol at moderate temperature. Operational simplicity, practicability and applicabi...

Microwave-accelerated preparation of Nـ alkyl 2ـ ketomethyl quinoline Derivatives

A series of Nـ alkyl 2ـ ketomethylquinoline derivatives were synthesis by reaction of benzoyl chloride derivatives with Nـ methyl quinaldine iodide in the presence of triethyl amine under microwave irradiation. Enaminone form of the product study by spectroscopy method. The result revealed the  Nـ alkyl 2ـ ketomethylquinoline the fixed enaminone tautomer.
