| 摘要: 本文研究了羰基钼(钨)与双(1-甲基咪唑-2-基)甲酮和双(1-甲基咪唑-2-基)甲烷以及双(1-甲基咪唑-2-基)乙烯的反应，获得了6个双齿螯合的双(1-甲基咪唑-2-基)甲酮，双(1-甲基咪唑-2-基)甲烷和双(1-甲基咪唑-2-基)乙烯四羰基金属衍生物，以及1个单齿配位的双(1-甲基咪唑-2-基)乙烯五羰基钨化合物。它们的结构通过红外，核磁以及X-射线单晶衍射分析得到确证。所有这些新化合物的电化学测试表明，它们只存在一个不可逆的氧化过程。 |

| Abstract: Reaction of bis(1-methylimidazole-2-yl)ketone [(mim)2C=O], bis(1-methylimidazole-2-yl)methane [(mim)2CH2] and bis(1-methylimidazole-2-yl)ethene [(mim)2C=CH2] with M(CO)5L ( M=Mo or W; L=CO or THF) has been investigated in this paper, which yields six bidentate chelating complexes (CO)4M(mim)2C=O, (CO)4M(mim)2CH2 and (CO)4M(mim)2C=CH2 as well as a monosubstituted pentacarbonyl tungsten derivative (CO)5W(mim)2C=CH2. These complexes have been characterized by IR and NMR spectroscopy, and their structures have been further confirmed by X-ray crystal diffraction. The electrochemical behavior investigated by cyclic voltammetry indicates that these newly synthesized complexes exhibit one irreversible oxidative process. CCDC: 740160, 7; 740161, 10. |
