First highly enantioselective epoxidation of alkenes with aldehyde/Oxone® Optically active aldehydes have been successfully used as catalysts for asymmetric epoxidations of unfunctionalized alkenes (ee up to 94%) by using Oxone... Ghanashyam,Bez,and,... - 《Tetrahedron Letters》 被引量: 6发表:...
Carboxylic acids such as hydrocinnamic acid can be also obtained by the heterogeneous catalytic aqueous-phase oxidation of aldehydes using silver(I)/copper(II) oxide [15], and by homogeneous catalytic oxidation of aldehyde using water-soluble N-heterocyclic carbene- and a silver(I)-catalyst with ...
Malonyldialdehyde- and Methylglyoxal-Induced Suppression ofEndothelium-Mediated Dilation of Rat Iliac Artery inResponse to Elevation of Blood Flow Arterial vessels dilate in response to an increase in blood flow rate (BFR). This control is based on ability of endotheliocytes to relax vascular smooth...
…reactions can be classified as oxidation, reduction, or hydrolysis. Oxidation is carried out by cytochrome P-450 monooxygenases, mixed-function amine oxidases, and alcohol and aldehyde dehydrogenases. The reactions mediated by cytochrome P-450 monooxygenases can make the chemical less toxic or more...

Direct aerobic oxidation of<italic>p </italic>-xylene using cobalt, manganese and bromide ion catalyst system, named the Amoco method, is a fundamentally important process to produce terephthalic acid in industry. However,
Processes are disclosed for the oxidation of alkanes such as, for example, propane, to form unsaturated carboxylic aldehydes and acids such as, for example, acrolein and acrylic acid. The processes utilize oxygen and recycle alkanes, e.g., propane, to the aldehyde reactor. The presence of the...
