Recent Research on Kinetics and Mechanism of Oxidation of Ethyl Diethylene Glycol by Ce(IV) Catalyzed by Ir(III) in Aqueous Sulphuric Acid Media

Kinetic research on oxidation by cerium(IV) of various types of organic compounds are well known. Ruthenium(III) and iridium(III) have been found to catalyse even at trace amounts among the distinct metal ion catalysis. In sulphuric acid media, the kinetics of iridium(III) catalysed oxidation of ethyl diethylene glycol by ceric sulphate were studied. The outcome suggests

For the assay of glibenclamide, a spectrophotometric and thermodynamic method is defined. The technique involves a glibenclamide charge transfer complexion reaction with 2,3-Dichloro-5,6-Dicyano-1,4-benzoquinone (DDQ) to form a very intense coloured charge transfer complex with a 1:1 stoichiometric ratio. Under tailored experimental conditions, the resulting coloured product was analysed at 474 nm. Beer-Lambert ‘s law was

Various biological activities have been found to demonstrate the compounds bearing sulfamoyl and acetamoyl groups. A series of O- and N-substituted derivatives, beginning with planetol (1), were synthesised in the present research work. Aq was used to treat the first N-methyl-4-hydroxyanilinium sulphate (1; planetol or metol) with various aryl sulfonyl chlorides (2a-j). Solution of sodium

The CuII complexes of (E)-2-(2-benzylidenehydrazinyl)-4-phenylthiazole, L1, (E)-2-(2-(4-chlorobenzylidene)hydrazinyl)-4-phenylthiazole, L2, and(E)-2-(2-(4-methoxybenzylidene)hydrazinyl)-4-phenylthiazole L3 ligands were prepared and spectroscopically characterised. The EPR spectroscopy indicates the formation for L2 and L3 of two complexation compounds, but for L1 of one main component. Hyperfine parameters A = 122(±1) G and g = 2.40(±0.01); A = 13(±2) G and g ⁇ =
