Heteroaryl-substituted arenes and heteroarenes were efficiently amidated through ruthenium-catalyzed C-H bond functionalizations with a variety of sulfonyl azides. Particularly, cationic ruthenium(II) complexes proved to be most effective and allowed nitrogenations of electron-rich and electron-deficient arenes with ample substrate scope.

We report the direct amidation of arene C-H bonds using sulfonyl azides as the amino source to release N2 as the single byproduct. The reaction is catalyzed by a cationic rhodium complex under external oxidant-free conditions in the atmospheric environment. A broad range of chelate group-containing arenes are selectively amidated with excellent functional group tolerance, thus opening a new avenue to practical intermolecular C-N bond formation.
