  含庞大双齿亚氨基亚氨基-N-杂环卡宾配体的钛苯氧基配合物的配位和反应性研究

  摘要：

  报道了包含芳基取代的无环亚氨基-N-杂环卡宾配体的早期过渡金属配合物的合成和结构表征。钛苯氧配合物的X射线晶体学研究证实，NHC配体通过类碳和亚胺氮原子配位形成八面体配合物。NMR光谱分析显示绕芳基键的旋转受到限制。尝试制备相应的钛亚氨基络合物的尝试反复导致分解产物，这可能是由于亚胺基团的反应性增强导致其从C ^亚胺配体支架上裂解而来。评估了苯氧配合物对乙烯聚合的催化活性。

  Reaction courses for formation of early transition metal phenoxides

  摘要：

  The 1:1 and 1:2 reactions of TiCl4 with Me3SiO-2,6-(CH3)2C6H3 produced TiCl3[O-2,6-(CH3)2C6H3]2(THF)2 (1) and TiCL2[O-2,6-(CH3)2C6H3]2(THF)2 (2), respectively, bearing six-coordinated geometry around Ti. The compound 2 assumes the cis-geometry regarding the two phenoxy groups and THF is coordinated in the trans position of the phenoxy groups. Similarly, the 1:1 and 1:2 reactions of NbCl5 with the trimethylsilyl phenyl ether provided NbCl4[O-2,6-(CH3)2C6H3]2(THF) (7) and NbCl3[O-2,6(CH3)2C6H3]2(THF) (8), respectively, with octahedron structure. The THF molecule again locates in the trans position of a phenoxy group in both cases and the two phenoxy groups of 8 locate in the cis position. Tungsten mono-phenoxide, WCl5[O-2,6(CH3)2C6H3]2 (12), also has octahedron structure. In cases of tungsten-bis-phenoxides, WCl4[O-2,6-(CH3)2C6H3]2 (13) and WCl4[O-2,6-(i-C3H7)C6H3]2 (14), the former has trans structure while the latter has cis structure regarding the phenoxy groups. A unique square pyramidal geometry has been observed in the tetrakis(phenoxy) tungsten, WCl[O-2,6-(CH3)2C6H3]4 (16).
