Allgemeine Beschreibung

9-Azabicyclo[3.3.1]nonane N-oxyl (ABNO) belongs to a sterically unhindered and stable class of nitroxyl radicals. It efficiently catalyzes the oxidation of alcohols to afford the corresponding carbonyl compounds. ABNO along with (MeObpy)CuI(OTf) (MeObpy =4,4′-dimethoxy-2,2′-bipyridine) comprises a catalytic system. This catalytic system is useful for the aerobic oxidation of all categories of alcohols.

A practical, three-step synthetic route to 9-azabicyclo[3.3.1]nonane N-oxyl (ABNO, 3), an unhindered, stable class of nitroxyl radical, has been developed. ABNO exhibits a highly active nature compared with TEMPO in the catalytic oxidation of alcohols to their corresponding carbonyl compounds.

Cu/TEMPO catalyst systems promote efficient aerobic oxidation of sterically unhindered primary alcohols and electronically activated substrates, but they show reduced reactivity with aliphatic and secondary alcohols. Here, we report a catalyst system, consisting of ((MeO)bpy)Cu(I)(OTf) and ABNO ((MeO)bpy = 4,4'-dimethoxy-2,2'-bipyridine;

Artikel

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.
