Preparation and applications of a polymer supported peroxotungstate complex as a novel polymeric oxidizing agent
A polymer supported anionic peroxotungstate compound [Amb](2)[W2O3(O-2)(4)] is prepared and characterized by conventional methods. Its use as a stoichiometric oxidizing agent for a variety of organic compounds is described. With this reagent alcohols are converted to the corresponding carbonyl compounds. Decarboxylation of a-hydroxy acids proceeds quantitatively. Also thiols are converted to disulfides, hydroquinones to quinones, benzylamines to carbonyl compounds, tertiary amines to the N-oxides, phosphines to phosphine oxides, and sulfides to sulfones. Deprotection of oximes and oxidative deprotection of silyl ethers proceed easily. (C) 2002 Elsevier Science B.V. All rights reserved.
