一般描述
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.
应用
用于醇的 Anelli 氧化反应的可回收催化剂。

TEMPO（2,2,6,6-四甲基哌啶氧基或2,2,6,6-四甲基哌啶1-氧基）及其衍生物在有机氧化反应催化剂中可以作为稳定的硝酰基使用。TEMPO由Lebedev和Kazarnovskii于1960年发现，其具有的稳定自由基性质得益于其庞大的取代基团阻碍了自由基与其他分子之间发生反应。
