arylboronic acids is achieved using KMnO4 as the sole and efficient oxidative system. This method provides an efficient protocol to construct regioselectively 2-arylquinoline N-oxides via radical cross-coupling reaction in moderated to good yields under mild conditions.

ruthenium–carbon nanotube nanohybrid was employed as a catalyst in the tandem transformation of nitrochalcones into quinoline N‐oxides. Partial reduction of the nitro group to a hydroxylamine, followed by in situ intramolecular condensation to the carbonyl afforded the quinoline‐N‐oxides in satisfactory to good yields. Reduction of the nitro group was selective and independent of changes in the reaction conditions

oxyarylation of quinoline N-oxides with terminal alkynes. The selectivity for C8-olefination and oxyarylation is sterically and electronically controlled. In the case of quinoline N-oxides (unsubstituted at the C2 position), only the olefination product was obtained irrespective of the nature of the alkynes. In contrast, oxyarylation was observed exclusively when 2-substituted quinoline N-oxides were reacted with
