, p. 2267 - 2275 (2017/03/24)
A Cu(OAc)2-catalyzed synthesis of 2-arylquinoline N-oxides with easily available arylamines is described. The main features of this reaction are mild reaction conditions, high functional-group tolerance, excellent regioselectivity, and good to excellent yields. This procedure is mild, operationally simple, and constitutes a greener approach to the arylation of quinoline N-oxides.

, p. 179 - 186 (2016/12/23)
An efficient protocol for the synthesis of 2-arylquinoline N-oxides has been developed via KMnO4-mediated cross-coupling reaction of quinoline N-oxides with aromatic hydrazines in moderated to good yields. The reactions proceeded efficiently over a broad range of substrates with excellent regioselectivity and functional group tolerance.
Carbon Nanotube-Ruthenium Hybrids for the Partial Reduction of 2-Nitrochalcones: Easy Access to Quinoline N-Oxides
