Selective aerobic oxidation in supercritical carbon dioxide catalyzed by the H5PV2Mo10O40 polyoxometalate.

Direct aerobic epoxidation of alkenes catalyzed by metal nanoparticles stabilized by the H5PV2Mo10O40 polyoxometalate.

Ag and Ru nanoparticles stabilized by H5PV2Mo10O40, prepared by a sequence of redox reactions and supported on alpha-alumina, were effective catalysts for the direct aerobic epoxidation of alkenes in the liquid phase.

Biphasic aerobic oxidation of alcohols catalyzed by poly(ethylene glycol)-stabilized palladium nanoparticles in supercritical carbon dioxide.

Mild and Efficient Oxidation of Alcohols with NaIO4 Catalyzed by a Manganese Porphyrin-polyoxometalate Hybrid Material

Efficient and selective oxidation of alcohols with NaIO4 catalyzed by an organic-inorganic hybrid material in which manganese(III)5,10,15,20-tetrakis(4-aminophenyl)porphyrin chloride, MnIII(TAPP)Cl, is covalently linked to a Lindqvist structure of polyoxometalate, Mo6O192-, at room temperature is reported. The effect of various parameters such as catalyst amount, solvent and oxidant were studie...

Supercritical carbon dioxide, a new medium for aerobic alcohol oxidations catalysed by copper-TEMPO.

The copper catalysed aerobic oxidation of selected alcohol substrates in supercritical carbon dioxide (scCO(2)), employing a range of simple copper(II) catalyst compounds, is here described. The copper acetate complex of polydimethylsiloxane (PDMS) functionalised pyridine (1), compound 2, has previously been synthesised and characterised by us and its solubility in scCO(2) demonstrated. Due to ...

Solubility Prediction of Drugs in Supercritical Carbon Dioxide Using Artificial Neural Network

The descriptors computed by HyperChem® software were employed to represent the solubility of 40 drug molecules in supercritical carbon dioxide using an artificial neural network with the architecture of 15-4-1. The accuracy of the proposed method was evaluated by computing average of absolute error (AE) of calculated and experimental logarithm of solubilities. The AE (±SD) of data sets was 0.4 ...
