摘要:The reaction of KBrO3 and NH2OH center dot HCl in situ generates NOx and Br anion, which combine with 2,2,6,6-tetramethylpiperidine-N-oxide (TEMPO) to construct a NO-activating dioxygen, Br-assisted, TEMPO-catalyzed aerobic oxidation of alcohols. Catalyzed by KBrO/NH2OH center dot HCl/TEMPO, various benzylic alcohols can be oxidized quantitatively to their corresponding carbonyl compounds under mild conditions. The easy handling and simple product separation make the process an attractive candidate for the oxidation of alcohols.
