title: Expedient C-H amidations of heteroaryl arenes catalyzed by versatile ruthenium(II) catalysts.
abstract: 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.
