Two smaller sections, which briefly discuss the mechanism of oxidation of alcohols with chromium(VI) and the influence of structure and stereochemistry of the alcohol on the oxidation rate complete the chapter.doi:10.1007/978-3-642-69362-5_4Professor Gianfranco Cainelli...
the alcohols are converted to aldehydes and ketones by the process of oxidation. this is one of the most important reactions in the field of organic chemistry. table of contents oxidation of alcohols to aldehydes and ketones what are the different types of alcohol? identification of alcohols ...
alcohol [27], the hemecis attached to the C-terminal part, in polyvinyl alcohol dehydrogenases [28, 29] to the N-terminal part of the enzyme. Besides for the mechanism of electron transfer between PQQ and hemec, QH-ADH type II is also interesting from an applied point of view since it...
Density functional theory (DFT) calculations have been performed to investigate the oxidation of alcohol to acetaldehyde, catalyzed by the (bpy)CuI-TEMPO/NMI catalytic system. Three pathways (path A, path B and path C) are presented. Our calculations indicate that path B is the favourable pathw...

The oxidation of methyl alcohol has been investigated in the liquid phase and the gas phase. In the latter case copper and aluminium were used as catalysts. Also the decomposition of methyl alcohol was investigated, oxygen being absent. These experiments were repeated using no catalyst. Some ...
When sec-phenethyl alcohol was labeled with 18O, 80% of the oxygen was retained in the ketone. Tests for the possible intervention of a free radical intermediate were carried out; the evidence was entirely negative. A mechanism featuring hydride abstraction is proposed, the first time for the ...

the acetate ligands are environed to serve two purposes: as a ligand for the Pd II center and as a base to deprotonate the Pd-bound alcohol, but acetic acid has not shown in previous bidentate ligands systems, so a mechanism is proposed on the basis of the mechanisms reported by the pi...
Spin trapping of Au-H intermediate in the alcohol oxidation by supported and unsupported gold catalysts. Electron paramagnetic resonance (EPR) spectroscopy and spin trapping were used to explore the mechanism of alcohol oxidation over gold catalysts. Reaction ... M Conte,H Miyamura,K Shu,... - ...
