Abstract

Recent groundbreaking work in the area of metal-catalyzed transformations of arynes, including the palladium-catalyzed cyclotrimerization of benzynes to form triphenylenes, 1 has provided novel new ways to rapidly construct fused aromatic polycycles. The metal- catalyzed cocyclization of arynes with alkynes has also been investigated. 2 In addition, metal-catalyzed carbonylative cycloadditions of arynes3 and the cocyclotrimerization of ...
