Abstract:
[structure: see text] Poly(ethylene glycol)-supported TEMPO (PEG-TEMPO) has been prepared, and its catalytic activity in the chemoselective oxidation of alcohols with stoichiometric amounts of organic or inorganic oxidants has been investigated. The new metal-free catalyst exhibits high activity and is easily removed from the reaction mixture by filtration. Recycling experiments showed that PEG-TEMPO can be reused up to six times with no loss of catalytic activity.

Oxidation of Alcohols
The process of oxidation in a chemical reaction is observed in any of the three forms:
Oxidation of Alkenes: Syn Dihydroxylation with Osmium Tetraoxide
Oxidation of Alkenes: Syn Dihydroxylation with Potassium Permanganate
Oxidation of Alkenes: Anti Dihydroxylation with Peroxy Acids
Aldehydes and Ketones with Alcohols: Hemiacetal Formation
Acid-Catalyzed Dehydration of Alcohols to Alkenes
