9-Azabicyclo[3.3.1]nonane N-oxyl

9-Azabicyclo[3.3.1]nonane N-oxyl (ABNO) may be employed for the aerobic oxidation of alcohols.

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)Cu^I(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.
