General description
FeCl3.6H2O/TEMPO (2,2,6,6-tetramethylpiperidine 1-oxyl radical) in the presence of silica gel has been employed as catalyst for oxidation of alcohols to the corresponding aldehydes and ketones. Doping of stable organic nitroxyl radical TEMPO, over different silica matrices affords reusable highly selective catalysts for various alcohol oxidation reactions. TEMPO-supported on silica gel catalyzed-Anelli oxidation of alcohols has been reported.
Application
Recyclable catalyst in the Anelli oxidation of alcohols.
