  Synthesis and characterization of oxadisilole fused benzo[b]triphenylene

  摘要：

  Palladium-catalyzed [2+2+2] cyclotrimerization reactions between benzyne and oxadisilole fused oxabicyclic alkenes afforded the exo-adducts. Deoxygenation with BF3 center dot OMe2 yielded mono- and bis-oxadisilole fused benzo[b]triphenylene. The photophysical properties of the oxadisilole fused benzo[b]triphenylenes were characterized.
