comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

:\<Iass spectra of letramethyl and tetraethyl lead and of dimethyl, diet llyl, and di-n-butyl mercury were obtained with a Co nsolidated 21102 mass spec trometer. Monoisotopic spectra were calculated by using the isotopic abundance derived from eac h spectrum. A variation in the lead isotope abundance was observed in the commercially available lead a lkyls. No variation was observed a mong t he...
متن کاملSome Oxidative Transformations of the Carbonyl Compounds and their Azomethine Derivatives*
Oxidative transformations of the aldehydes, ketones, and their azomethine derivatives such as hydrazones, Schiff bases, azines, and oximes are presented and discussed. The oxidants used have been hydrogen peroxide in the presence of selenium compounds as catalysts, peroxycarboxylic acids, and eerie ammonium nitrate. Some of reported reactions have practical value in the synthesis of phenols, es...
