Abstract

Found at the core of many discotic liquid crystals, triphenylenes can now be synthesized efficiently by the palladium-catalyzed trimerization of arynes, including those containing donor and acceptor substituents [Eq. (a); R=OMe, F].

Keywords: Arynes; Cyclotrimerizations; Palladium; Triphenylenes.
