In this article, the catalytic activity of bis[2-(p-tolyliminomethyl)phenolato] copper(II) complex was studied, for the first time, in the oxidation of various primary and secondary alcohols to the corresponding aldehydes or ketones. The effect of different solvent was studied in the oxidation of benzyl alcohol and methanol was chosen as the reaction medium. Also the effect of different oxidant...

The production of vanillin from lignin-derived vanillyl alcohol poses a great deal research interest because the availability renewable lignin in abundant quantities. In present study, series copper-doped ceria (CeO2) catalysts were prepared by modified template-assisted method, characterized various techniques, and explored for oxidation to with molecular oxygen as oxidant at normal atmospheri...

an efficient protocol for the selective oxidation of primary alcohols to aldehydes withh5io6/v2o5 in ionic liquid [bmpy][pf6] has been developed. high yields of the products, mildreaction conditions and simple experimental procedure make this protocol complementary tothe existing methods. the catalyst can be reused for several times without obvious loss of thecatalytic activity.

Octylphenol polyethoxylate (OPEO(n)) biodegradation by Pseudomonas putida S-5 under aerobic conditions is initiated by the oxidation of its terminal alcohol group by alcohol dehydrogenase. A DNA fragment, containing an alcohol dehydrogenase gene (adh1), was isolated using a combination of degenerate PCR and inverse PCR. The predicted translation product of adh1 showed significant sequence simil...

The reaction parameters for the Laccase/TEMPO system in the aerobic oxidation of aromatic alcohols were investigated. The optimized concentrations of laccase and alcohol were found to be 10 U/ml and 160 mM respectively. Under these conditions the use of 9 mol % TEMPO led to good conversions within 4 h. The optimum temperature for the reaction was found to be above room temperature (around 30°C).

The Pd(OAc)(2)/pyridine catalyst system is one of the most convenient and versatile catalyst systems for selective aerobic oxidation of organic substrates. This report describes the catalytic mechanism of Pd(OAc)(2)/pyridine-mediated oxidation of benzyl alcohol, which has been studied by gas-uptake kinetic methods and (1)H NMR spectroscopy. The data reveal that turnover-limiting substrate oxida...

In the heterogeneous catalyst i-Pd(OAc)2(TPPTS)2, Pd(II) was reduced to Pd(0) by using different alcohol solvents, and catalyst’s activity studied in aerobic oxidation of benzyl alcohol. We effects impregnation time ethanol as a solvent use various alcoholic solvents on size palladium nanoparticles. found that reduction alcohols yielded nanoparticles were active As determined DLS, TEM, zeta pot...
