[(η3-C3H5)M(CO)2(κ3-tpm)]+ (M = Mo, W). The coordination mode of the tridentate ligand was resolved by 1H NMR spectroscopy. This study further covers the model systems with the bidentate ligands bis(pyrazolyl)methane (bpm) and bis(1,3-dimethylpyrazolyl)methane (Me4bpm). All compounds under the study were characterized by the infrared spectroscopy. The structures of two molybdenum compounds [(η3-C3H5)Mo(CO)2(κ2-bpm)Cl]
摘要该研究描述了烯丙基
钼和
钨配合物[(η3-
C3H5)M(CO)2(NCMe)2Cl](M = Mo,W)与三(
吡唑基)
甲烷(tpm)的反应。该三齿蝎形
配体产生两种类型的产物。从非
水介质中分离出中性κ2复合物[(η3- )M(CO)2(κ2-tpm)Cl](M = Mo,W),而
水性处理则得到阳离子κ3复合物[( η3- )M(CO)2(κ3-tpm)] +(M = Mo,W)。三齿
配体的配位模式通过1 H NMR光谱解析。这项研究进一步涵盖了具有双齿
配体双(

甲烷(bpm)和双(
1,3-二甲基吡唑基)
甲烷(Me4bpm)的模型系统。通过红外光谱对所研究的所有化合物进行表征。两种
