Synthesis of Triphenylene via the Palladium–Catalyzed Annulation of Benzyne

Abstract

Abstract This chapter describes the procedure for synthesis of triphenylene via the palladium–catalyzed annulation of benzyne. It presents some of the important points to be considered, the conditions that need to be maintained, characterization data, and the reagents required, as well as the techniques used and the equipment setup that are vital to carrying out the process. The chapter also describes the hazards associated with working with chemicals and the ways to deal with these hazards. Triphenylene, a symmetrical aromatic hydrocarbon, began receiving significant attention from the scientific community following the discovery of discotic liquid crystals (DLCs) in 1977. Triphenylene's symmetry and thermal and chemical stability make it an ideal core for DLCs.
