• Bifunctional carbosilane dendrons for the immobilization of zirconocene catalysts on silica

  日期：——

  A method for the preparation of bifunctional carbosilane dendrons has been developed and used to synthesize first- and second-generation dendrons containing [Cp2MCl2] end-groups (M = Ti, Zr; Cp = cyclopentadienyl) and Si–Cl focal-point bonds. These dendrons have been fully characterized in solution and, in the case of the zirconium derivatives, immobilized on an amorphous silica surface and tested as ethylene polymerization catalysts. The immobilization was quantitative and quite stable under the conditions of the catalysis.

  我们开发了一种制备双功能碳硅烷树枝状化合物的方法，并利用这种方法合成了第一代和第二代树枝状化合物，这些树枝状化合物含有[Cp2MCl2]端基（M = Ti、Zr；Cp = 环戊二烯基）和硅-氯焦点键。这些树枝状化合物在溶液中得到了充分的表征，就锆衍生物而言，它们被固定在无定形二氧化硅表面，并作为乙烯聚合催化剂进行了测试。在催化条件下，固定化是定量和相当稳定的。
