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.
