Ruthenium‐Catalyzed Oxidative Homo‐Coupling of 2‐Arylpyridines

A ruthenium‐catalyzed oxidative homo‐coupling reaction of 2‐arylpyridines via CH activation was developed. The reaction could tolerate various functional groups on both the aryl and the pyridyl rings to afford a series of dimerized products with iron(III) chloride (FeCl3) as a stoichiometric oxidan...

Zusammenfassung:A ruthenium‐catalyzed oxidative homo‐coupling reaction of 2‐arylpyridines via CH activation was developed. The reaction could tolerate various functional groups on both the aryl and the pyridyl rings to afford a series of dimerized products with iron(III) chloride (FeCl3) as a stoichiometric oxidant. A tentative mechanism was proposed for this oxidative CH/CH homo‐coupling.
