Silver-Catalyzed 2-Pyridyl Arylation of Pyridine N-Oxides with Arylboronic Acids at Room Temperature
A novel direct arylation of pyridineN-oxides with arylboronic acids through C-H functionalization has been developed. This new reaction is performed at room temperature using catalytic silver(l) nitrate in the presence of potassium persulfate and give 2-pyridyl arylation derivatives of pyridineN-oxides.

visible-light-promoted C2 selective arylation of quinoline and pyridineN-oxides, with diaryliodonium tetrafluoroborate as an arylation reagent, using eosin Y as a photocatalyst for the construction of N-heterobiaryls was presented. This methodology provided an efficient way for the synthesis of 2-aryl-substituted quinoline and pyridineN-oxides. This strategy has the following advantages: specific regioselectivity
