The oxidation is highly selective for secondary alcohols and does not oxidize other sensitive functional groups such as amines and sulfides. Article Views are the COUNTER-compliant sum of full text article downloads since November 2008 (both PDF and HTML) across all institutions and individuals. [11], The Oppenauer oxidation is also used in the synthesis of lactones from 1,4 and 1,5 diols. Liu (2006). P Pauson-Khand reaction. Figure 4, Transition state of intramolecular MPV reduction. Janusz Lewiński, Andrew E. H. Wheatley. Diana-Lucía Grajales, Lina-María González, Aída-Luz Villa. Missing or empty |title= (help). A.; Van Bekkum, H.; Huskens, J. The acetone is coordinated to the aluminium which activates it for the hydride transfer from the alkoxide. This method lead to the reduction of substituted acetophenones in up to 83% e.e. "Meerwein–Ponndorf–Verley reduction over Heterogeneous Catalysts". Knorr pyrazole synthesis. Wu Li, Zhengli Duan, Ru Jiang, and Aiwen Lei . While commercial aluminim isopropoxide is available, the use of it often requires catalyst loadings of up to 100-200 mol%. The LibreTexts libraries are Powered by MindTouch® and are supported by the Department of Education Open Textbook Pilot Project, the UC Davis Office of the Provost, the UC Davis Library, the California State University Affordable Learning Solutions Program, and Merlot. Swern oxidation) or Dess–Martin oxidation due to its use of relatively mild and non-toxic reagents (e.g. "Highly Efficient, Catalytic Meerwein–Ponndorf–Verler Reduction with a Novel Bidentate Aluminum Catalyst". Synthesis. Files available from the ACS website may be downloaded for personal use only. One-pot formation of aza-enolates from secondary amines and condensation to esters and alkyl bromides. The method has been largely displaced by oxidation methods based on chromates (e.g. Kevin P. Yeagle, Darryl Hester, Nicholas A. Piro, William G. Dougherty, W. Scott Kassel, Christopher R. Graves. 126 (45): 14796–14803. Cyclometalated phosphine-based Ir(III) pincer complex as a catalyst for Oppenauer-type oxidation of alcohols. Catalytic oxidative dehydrogenation of carveol to carvone over the phthalocyanine complex FePcCl 16 immobilized on the mesoporous silica SBA-15. After the reaction is run the hydride-source portion of the molecule can be removed. Synthetic Scope of Alcohol Transfer Dehydrogenation Catalyzed by Cu/Al2O3: A New Metallic Catalyst with Unusual Selectivity. [13], Another side reaction is the Tischenko reaction of aldehyde products with no α-hydrogen, but this can be prevented by use of anhydrous solvents. This article is cited by [2] The alcohol is oxidized with aluminium isopropoxide in excess acetone. Perkin reaction. "The Mechanism of Aluminum-Catalyzed Meerwein-Schmidt-Ponndorf-Verley Reduction of Carbonyls to alcohols".
