Arynes participate in three‐component coupling reactions with N, S, P, and Se functionalities to yield 1,2‐heteroatom‐difunctionalized arenes. Using 2‐iodophenyl arylsulfonates as benzyne precursors, we could effectively add magnesiated S‐, Se‐, and N‐nucleophilic components to the strained triple bond. In the same pot, addition of electrophilic N, S, or P reagents and a copper(I) catalyst trapped
Arynes参与具有N,S,P和Se官能团的三组分偶联反应,从而生成1,2-杂原子双官能化的芳烃。使用2-碘苯基芳基磺酸盐作为苯炔前体,我们可以有效地将镁化的S-,Se-和N-亲核组分添加到应变的三键上。在同一个锅中,添加亲电的N,S或P试剂和铜(I)催化剂会俘获中间体芳基格里亚德中间体,从而产生各种1,2-双官能化的芳烃。
