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.
