Title:
アンサ-メタロセン錯体のラセモ選択的製造方法
Document Type and Number:
Japanese Patent JP2007536316
Kind Code:
A
Abstract:
Ansa-metallocene complexes are racemoselective prepared by reacting a dianionic ligand starting compound in the form of an alkali metal, alkaline earth metal or magnesium monohalide salt with a transition metal amide compound having an uncharged Lewis base ligand. Racemoselective preparation of ansa-metallocene complexes of formula (I), includes reacting a ligand starting compound of formula (II) with a transition metal compound of formula (III). (LB) yM 1>(NR 3>R 4>)X x-1 (III) R 1>, R 1>', R 2>, R 2>', R 4>H or a 1-40C organic radical; R 3>a 1-40C organic radical; T, T' : a 1-40C divalent organic which together with the cyclopentadienyl ring forms at least one further optionally saturated, optionally substituted ring system which has a ring size of 5-12 atoms, where T and T' may contain heteroatoms, e.g. Si, Ge, N, P, As, Sb, O, S, Se or Te, within the ring system fused to the cyclopentadienyl ring; A : a bridge containing a divalent atom or a divalent group; M 1>an element of group 3, 4, 5 or 6 of the Periodic Table of the Elements or the lanthanides; X : an organic or inorganic radical which can be substituted by a cyclopentadienyl anion; x : 3-6; M 2>an alkali metal, an alkaline earth metal or a magnesium monohalide fragment; p : 1 in the case of doubly positively charged metal ions or 2 in the case of singly positively charged metal ions or metal ion fragments; LB : an uncharged Lewis-base ligand;and y : 0-6. Independent claims are also included for: (1) a process of racemoselective preparation of ansa-metallocene complexes of formula (IV), comprising reacting the metallocene complex of the formula (I) prepared by the above process with suitable elimination reagents in a subsequent reaction step to form the metallocene complex of the formula (IV); and (2) the transition metal compound of the formula (III) as above. R 1>, R 1>', R 2>, R 2>', A, M 1>, X, T, and T' : as defined above. [Image].
