  Abstract:

  The Pd-catalyzed condensation of 2-bromostyrene and   2-chloroaniline derivatives yields stable diphenylamine   intermediates, which are selectively converted to five-, six-, or   seven-membered heteroaromatics (indoles, carbazoles, acridines,   and dibenzazepines). The selectivity of these intramolecular   transformations is uniquely ligand-controlled and offers   efficient routes to four important classes of heterocycles from a   common precursor.
