  First silver complexes of tetrahydropyrimid-2-ylidenes

  摘要：

  The syntheses and characterizations of homoleptic silver(I) carbene complexes of the type LAgCl (3) and [L2Ag](2)(+)[Pd2Cl6](2-) (4) (L = dime sityltetrahyd ropyrimid-2-ylidene) are described. 3 was obtained by reaction of the corresponding tetrahydropyrimidinium salt with silver(I) oxide. Subsequent reaction of 3 with Pd(CH3CN)(2)Cl-2 afforded complex 4. The crystal structure of 3 has been determined to be a monomer in the solid state. The C-13 NMR spectra of both 3 and 4 exhibit C-13-Ag-107,Ag-109 coupling in solution. Furthermore, both compounds show a downfield shift of the carbene carbon of about 20 ppm to about 205 ppm in the C-13 NMR compared to five-membered ring silver(I) carbene complexes. Unlike other silver-carbene complexes, 3 does not undergo ligand exchange and can thus not be used for carbene transfer to other metals. (C) 2004 Elsevier B.V. All rights reserved.

  A solid catalyst component useful for the (co)-polymerization of olefins is disclosed. The catalyst component is prepared by reacting an activated magnesium halide composite support with a halogenized transition metal compound and a chelating diamide compound in the presence of organo-magnesium as a promoting agent and halogenized silicon or boron compounds as an activator. The catalyst component can be used with an organo-aluminum compound to provide a solid catalyst system that is compatible with slurry and gas phase polymerization processes. Linear low density polyethylene (LLDPE) produced using the catalyst component of the present invention displays a low molecular weight distribution, improved co-monomer incorporation, low content of the low molecular weight component, and excellent morphological properties such as spherical shape and high bulk density.

  本发明公开了一种用于烯烃（共）聚合的固体催化剂组分。该催化剂组分是在有机镁作为促进剂和卤化硅或硼化合物作为活化剂的存在下，通过活化卤化镁复合载体与卤化过渡金属化合物和螯合二酰胺化合物反应制备的。催化剂组分可与有机铝化合物一起使用，以提供一种与浆料和气相聚合工艺兼容的固体催化剂体系。使用本发明的催化剂组分生产的线性低密度聚乙烯（LLDPE）具有分子量分布低、共聚单体掺合度提高、低分子量组分含量低以及球形和高体积密度等优异的形态特性。
