实现了新型Hg(OTf)(2)催化芳烯环化反应，催化周转率高达200次。该反应通过原位形成的有机聚合物中间体的TfOH使烯丙基羟基质子化而产生阳离子。随后的平稳变性使催化剂再生。
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.
