Polyfused chalcogenophenes are prepared in one step through polyelectrophilic cyclization of polyynes using the ambiphilic reagent MeACl (A = S, Se, or Te). Up to four new rings have been generated under mild conditions, including thiophenes, selenophenes, and tellurophenes.

Polyynes到多环化合物:形成多聚硫属元素的多米诺反应

第一步,通过使用多相试剂MeACl(A = S,Se或Te)通过聚炔的多亲电环化制备多聚硫属元素。在温和条件下,已经产生了多达四个新的环,包括噻吩,硒烯和碲烯。
