Intramolecular (3+2) cycloaddition reactions involving benzyne and ynamides as three-atom components have been accomplished through the utilization of benzyne precursors having a linking functionality. The ambivalent nature of the intermediate indolium ylide, which exhibits both nucleophilic and electrophilic properties at its C2 atom, is thus brought to light in this approach.
涉及苯炔和炔胺作为三原子组分的分子内 (3+2) 环加成反应已通过利用具有连接功能的苯炔前体完成。因此,在这种方法中揭示了中间体吲哚叶立德的矛盾性质,它在其 C2 原子上同时表现出亲核和亲电子性质。
