PURPOSE:In the oxidation of an alcohol into the corresponding carbonyl compound, an ion-exchange type laminar clay catalyst is used to effect the oxidation with oxygen to economically improve the yield without use of an oxidizing reagent such as a permanganate salt. CONSTITUTION:An ion-exchange ...
with these oxidizing agents that don't break carbon-carbon bonds. So I'll get to what they are in a second, but even before we know what the reagents are, we could already jump into a practice problem. What I'm wondering is out of these four molecules here, which of th...
therefore, some debate has been arisen about the nature of the electron-transfer and transition states in the rate-determining steps. In connection with the multi-equivalent oxidants such as in case of permanganate ion
First, the solubility of different cerium(IV) salts in ILs was tested. Second, the oxidation of benzyl alcohol to benzaldehyde was studied by in-situ spectroscopic techniques (NMR, FTIR) to obtain some insight in the mechanism. Finally, the reaction was extended to other substrates, among them...
Ultrafine gold nanoparticles on the magnetic cored dendrimer were used as a green sustainable catalyst for the aerobic oxidation of alcohol under mild reaction conditions. The catalyst was recovered and reused by simple magnetic separation up to five catalytic cycles with no appreciable loss in catalyst...

The mechanism for the permanganate oxidation of imines to amides is discussed; two reaction paths are considered, one in which water adds to the imine followed by an oxidation of the amino alcohol to the amide by the permanganate ion, while the other—a minor reaction path under the present ...
The optically active carboxylic acid of general formula (V) can be produced by the oxidation of the corresponding optically active primary alcohol with potassium permanganate, or by Grignard reagent synthesis of an optically active alkyl hal... T Shoji,S Takehara,T Fujisawa,... - EP 被引量:...
The reaction rates were found to vary linearly with [Co3+] and [Alcohol]. From the effect of acidity and of [HSO −4 ] in H2SO4 medium on the reaction rates it was concluded that in HClO4 medium CoOH2+ species were the active entities while in H2SO4 medium Co3+ as well as ...
Calcination at 600 °C allows the formation of macro- and mesopores, in contrast to similar materials that often show a bulk structure. Catalytic tests show that La0.9Ce0.1CoO3 is highly active for benzyl alcohol oxidation with molecular oxygen, with both conversion and selectivity above 95% (...
