title: Ruthenium-catalyzed cross-dehydrogenative ortho-N-carbazolation of diarylamines: versatile access to unsymmetrical diamines.
abstract: The dehydrogenative C-N cross-coupling of unprotected, secondary anilines through ortho-N-carbazolation has been achieved using a Ru catalytic system with O2 as the terminal oxidant. The reactions proceed in an intermolecular fashion, selectively in the ortho position. Implications for the field of organic synthesis are discussed.
