A sensitive amine-responsive disassembly of self-assembled AuI -CuI double salts was observed and its utilization for the synergistic catalysis was enlightened. Investigation of the disassembly of [Au(NHC)2 ][CuI2 ] revealed the contribution of Cu-assisted ligand exchange of N-heterocyclic carbene (NHC) by amine in [Au(NHC)2 ]+ and the capacity of [CuI2 ]- on the oxidative step. By integrating the
观察到自组装的AuI-CuI复盐的敏感的胺反应分解,并启发了其在协同催化中的应用。对[Au(NHC)2] [CuI2]的分解研究表明,胺在[Au(NHC)2] +中的铜辅助配位交换了N-杂环卡宾(NHC)和[CuI2]的容量-在氧化步骤上。通过整合编码在d10金属配合物的响应行为和固有催化功能中的暗示信息,开发了一种用于胺的氧化羰基化的催化剂。该方法的优势已在温和的反应条件和明显扩大的范围上得到了明显体现(51个实例)。伯胺和空间仲胺都可以用作底物。金和铜中心的协同反应
