Amphiphilic Polypyridyl Ruthenium Catalyzed, Photoredox‐Mediated C−H Arylation of Heteroarenes with Aryl Diazonium Salts

Abstract Visible light mediated direct C−H arylation of wide range of heteroarenes with aryl diazonium salts catalyzed by amphiphilic polypyridyl ruthenium complex is reported. Using a visible light activated catalyst, mild conditions for arylation of a variety of heteroarenes is achieved in good to excellent yields. A broad substrate scope was demonstrated compatible with various functional groups and exhibiting modest levels of regioselectivity.
