  Hg(OTf)₂-Catalyzed Arylene Cyclization

  摘要：

  Novel Hg(OTf)(2)-Catalyzed arylene cyclization was achieved with highly efficient catalytic turnover (up to 200 times). The reaction takes place via protonation of allylic hydroxyl group by in situ formed TfOH of an organomercuric intermediate to generate a cationic species. Subsequent smooth demercuration regenerates the catalyst.
