일반 설명

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.

애플리케이션

Recyclable catalyst in the Anelli oxidation of alcohols.

TEMPO (2,2,6,6-Tetramethylpiperidinyloxy or 2,2,6,6-Tetramethylpiperidine 1-oxyl) and its derivatives are stable nitroxy radicals used as catalysts in organic oxidation reactions. TEMPO was discovered by Lebedev and Kazarnovskii in 1960. The stable free radical nature of TEMPO is due to the presence of bulky substituent groups, which hinder the reaction of the free radical with other molecules.
