title: Rh(III)-catalyzed C-H bond activation along with "rollover" for the synthesis of 4-azafluorenes.
abstract: An intramolecular reaction of 3-alkynyl and 3-alkenyl-2-arylpyridines selectively gave 4-azafluorene compounds in the presence of a catalytic amount of [Cp*RhCl(2)](2) and Cu(OAc)(2). Pyridine-directed C-H bond activation along with "rollover" are likely to be key steps of this transformation.
