ized dicopper(I,I)-NHC complex (1) features both terminal and bridging coordination modes of NHC within the same molecule, and catalyzes dual ortho-C–H functionalization of diaryl amines for the hydroarylation of alkynes. A bimetallic construct in catalyst 1 allows sequential activation of ortho-C–H bonds of two aryl units to furnish a wide variety of 9,10-dihydroacridinederivatives without the explicit
吡啶和吗啉官能化的二铜( I , I )-NHC复合物( 1 )在同一分子内具有NHC的末端和桥连配位模式,并催化二芳基胺的双邻位-C-H官能化以实现炔烃的氢芳基化。催化剂1中的双金属结构允许连续激活两个芳基单元的邻-C-H键,以提供多种9,10-二氢吖啶衍生物,而无需明确使用导向基团。
