Two bis-(propyl-imidazolium)-napthalenediimide (NDI) salts were prepared and used as N-heterocyclic carbene (NHC) precursors for the preparation of dimetallic complexes of rhodium and iridium. Infrared spectroelectrochemical studies indicate that the metals are sensitive to changes in the electronic state of the NDI moiety. The catalytic behavior of the rhodium and iridium complexes was tested in the cycloisomerization of alkynoic acids, where the complexes showed effective redox-switching properties.
两种双-(丙基-咪唑基)-萘二酰亚胺(NDI)盐被制备出来,并被用作 N-杂环卡宾(NHC)前体,用于制备铑和铱的二金属配合物。红外光谱电化学研究表明,金属对 NDI 部分的电子状态变化敏感。铑和铱配合物的催化行为在炔酸的环异构化反应中进行了测试,其中配合物表现出有效的氧化还原开关性质。
