  unactivated secondary Csp3−H bond has been achieved using IrIII catalysts. The introduced N,N’‐bichelating ligand plays a crucial role in enabling iridium–nitrene insertion into a secondary Csp3−H bond via an outer‐sphere pathway. Mechanistic studies and density functional theory (DFT) calculations demonstrated that a two‐electron concerted nitrene insertion was involved in this Csp3−H amidation process

  首次使用Ir III催化剂实现了高度区域选择性的分子间磺酰胺化未激活的二级Csp 3 -H键。引入的N，N'-螯合配体在使铱-氮烯通过外球途径插入Csp 3 -H二级键中起着至关重要的作用。机理研究和密度泛函理论（DFT）计算表明，该Csp 3 -H酰胺化过程涉及二电子协同的氮插入。该方法可耐受各种直链和支链的N-烷基酰胺，并能有效地获得各种γ-磺酰胺基取代的脂肪族胺。
