  Formation and crystal structures of (C5H5)3Sm(THF) and (C5H5)3Dy(THF)

  摘要：

  The title complexes were formed by refluxing the complexes [Cp(2)SmO (CH2)(4)CH3](2) and [Cp(2)DyS(CH2)(3)CH3](2) (Cp = C5H5) in THF and studied by X-ray crystallography. The complexes are both monomers with the central metal coordinated by three Cp ring centroids and one THF molecule to form a distorted tetrahedral geometry. The Cp groups coordinate to the metal in a eta(5)-fashion with the average Sm-C distance of 2.75(2) Angstrom and Dy-C distance of 2.70(1) Angstrom. The Sm-O and Dy-O bond lengths are 2.512(8) and 2.462(6) Angstrom, respectively. The comparison of some significant structural parameters of the title complexes with those of the known isostructural complexes Cp(3)Ln . THF (Ln = La, Pr, Nd, Gd and Lu) conformed to the ''lanthanide contraction'' effect.

  摘要：

  水解后，在45°C下用Cp 3 Ln / NaH（Cp =环戊二烯基，Ln =稀土金属）还原1-己烯，得到己烷。Cp 3 Ln的还原活性在很大程度上取决于三价稀土离子的离子半径。早期稀土还原1-己烷的活性和选择性都比重稀土高。Cp 3 Ln / NaH系统可用于区域选择性还原包含末端碳碳双键以及内部产率高的二烯。选择性为100％。而且，Cp 3 Ln / NaH系统能够催化烯烃的氢化。

  A number of paramagnetic silylated d1 group 4 metallates were prepared by reaction of potassium tris(trimethylsilyl)silanide with group 4 metallates of the type K[Cp2MCl2] (M = Ti, Zr, Hf). The outcomes of the reactions differ for all three metals. While for the hafnium case the expected complex [Cp2HfSi(SiMe3)3}2]− was obtained, the analogous titanium reaction led to a product with two Si(H)(SiMe3)2
