Carbon Networks Based on Benzocyclynes. 6. Synthesis of Graphyne Substructures via Directed Alkyne Metathesis
摘要:
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.
