Thermal treatment of indenyl-functionalized imidazolium salts and N-heterocyclic carbenes with Ru3(CO)12 gave different products. The normal mononuclear metal complexes (2a, 2b) were obtained via direct reaction of indenyl-functionalized imidazolium salts (1a, 1b) with Ru3(CO)12. Unexpected intramolecular C-H activated products (3a, 3b, 4a, 4b) were obtained via thermal treatment of corresponding indenyl-functionalized N-heterocyclic carbenes. All complexes were determined by 1H NMR, 13C NMR, IR spectra and elemental analysis. The molecular structures of 2b, 3a, 3b and 4b were determined by X-ray diffraction.
热处理茚基功能化的咪唑翁盐和 N-杂环卡宾与 Ru3(CO)12 得到不同的产物。通过茚基功能化的咪唑翁盐（1a、1b）与 Ru3(CO)12 的直接反应得到正常的单核金属配合物（2a、2b）。通过相应的茚基功能化的 N-杂环卡宾的热处理得到意想不到的分子内 C-H 活化产物（3a、3b、4a、4b）。所有配合物均通过 1H NMR、13C NMR、IR 光谱和元素分析确定。通过 X 射线衍射确定了 2b、3a、3b 和 4b 的分子结构。
