title: Carbon networks based on benzocyclynes. 6. synthesis of graphyne substructures via directed alkyne metathesis.
abstract: Intramolecular ring closing alkyne metathesis afforded the graphyne biscyclyne (3) in high macrocyclization yield and good overall yield. This methodology also furnished the tris[12]cyclyne 4, which contains the longest linear diphenylacetylene conjugation pathway for any graphyne substructure based on the tribenzo[12]cyclyne core.
