Oxadisilole fused triptycene and extended triptycene: precursors of triptycyne and extended triptycyne

J Org Chem. 2010 Nov 5;75(21):7332-7. doi: 10.1021/jo1016025.

Abstract

With benzobisoxadisilole 1 as a 1,4-benzdiyne equivalent, oxadisilole fused triptycene 5 and extended triptycene 6 were synthesized. Triptycenes 5 and 6 are new precursors of triptycyne 7 and extended triptycyne 8 respectively via the phenyliodination/fluoride induced elimination protocol. Using these two arynes, a series of triptycene derivatives were synthesized.
