Reaction of these complexes 2 with AgPF6 afforded Cl-bridged cationic binuclear iridium and rhodium complexes 3.

  日期：2018.6.1

  Unfunctionalized indoles can be directly converted into 3,3′-spirocyclic indolenines and indolines upon reaction with electrophilic dihalides in the presence of t-BuOK/BEt3. This double C–C bond forming reaction, which simultaneously generates a quaternary spirocyclic center, typically proceeds in high yield and has good functional group tolerance. In contrast to existing dearomatizing spirocyclization

  在t -BuOK / BEt 3存在下，与亲电二卤化物反应时，未官能化的吲哚可直接转化为3,3'-螺环吲哚和二氢吲哚。这种双CC键形成反应，同时生成一个季螺环中心，通常以高收率进行并且具有良好的官能团耐受性。与现有的脱芳香化螺环化方法相比，不需要制备预官能化的芳香族前体，从而能够一步一步从简单的可商购的芳香族化合物中快速获得有价值的螺环产品。
