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...

The production of ethylen tially attractive, since the carbon source than petrol bonylation using methyl f used as the catalyst. Met were formed along with of formaldehyde source, r paraformaldehyde, 1,3,5-t The highest yields of met as the source of formalde and limited the rate of ca the highest yields of meth produce these products at methanesulfonic acid is a the reactive intermediates
متن کاملAmmonium nitrate as an efficient and green reagent for the oxidation of alcohols into their corresponding carbonyl compounds in the presence of heteropoly acids
Simple, cheap and green protocol for effective conversion of alcohols to corresponding carbonyl compounds in the presence of H14[NaP5W30O110] and ammonium nitrate is reported. The products were characterized by FT-IR and comparison of their physical properties with those reported in the literatures. The progress of the reaction was monitored by thin layer chromatography (TLC) technique. The ali...
متن کاملAntitumor effects of a selenium heteropoly complex in K562 cells.
The aim of this study was to investigate the anti-tumor effects and mechanism of the selenium heteropoly compound (C(2)H(10)N(2))(5)(NH(4))(4)H(2)[Se(2)W(10)V(8)O(62)].9H(2)O (SeWV) in K562 cells. The results showed that 0.32-10.15 x 10(-3) mmol/l SeWV could significantly inhibit the proliferation of K562 cells in vitro, as determined by the MTT assay, with IC(50) values of 3.07 and 2.69 x 10(-...
