摘要： 合成了四个含吡啶鎓阳离子的氮杂环卡宾钯(II)三碘配合物. 通过核磁共振谱和元素分析对它们进行了表征. 同时利用X射线单晶衍射确定了其中两个配合物的晶体结构. 研究表明该系列配合物对Suzuki-Miyaura偶联具有催化活性.  

关键词: 氮杂环卡宾, 钯, 催化, Suzuki-Miyaura偶联

Abstract: Four air stable palladium(II) triiodine complexes containing N-heterocyclic carbenes with pyridinium groups [(NHC)PdI3] have been synthesized and characterized by NMR and elemental analyses. The molecular structures of two compounds have been confirmed by single-crystal X-ray diffraction. These NHC-Pd(II) complexes are active catalysts in the Suzuki-Miyaura cross-coupling reactions under atmosphere conditions with moderate conversion

Key words: N-heterocyclic carbene, palladium, catalysis, Suzuki-Miyaura coupling
