The Liquid-phase Oxidation of Hydrocarbons with Molecular Oxygen. II. A Highly Selective Formation of α-Tetralone by the Metal-catalyzed Oxidation of Tetralin in the Presence of N,N-Dialkylamides

摘要: The metal-ion catalyzed oxidation of tetralin was carried out in different solvents which metal salts tend to be soluble. It found that, for the production α-tetralone, a chromium salt is best catalyst among first-transition-metal employed, while N,N-dialkylamides are or additives. For example, tris(acetylacetonato)chromium(III)-catalyzed presence N,N-dimethylacetamide, α-tetralone obtained 93.0% yield at 27.2% conversion. decomposition α-tetralyl hydroperoxide (THP) with catalysts also N,N-dimethylformamide order elucidate formation mechanism N,N-dialkylamides. concluded that product distribution mainly depends on THP, and seem promote reaction α-tetralylperoxyl radical w...
