Process for Preparing Dialkyl Oxide Methallocenes or Diaryl Oxide metallocenes

摘要

The invention bridged stereo rigid, Guardia di alkoxide pure stereo meojeok metallocene, diaryl oxide Q Sen and preferably a metal (Cp) (Cp ') M (OR ³ ) ₂ of diphenoxylate green side of the equation metallocene (where, Cp = cyclopentadienyl cyclopentadienyl, indenyl or fluorenyl radical, Cp '= Cp groups of one, Q = Cp and Cp' between single-or multi-membered bridged (R ¹ -ZR ² ) b, where, R ¹ and R ² may be the same or different and each is a hydrogen atom, C ₁ - C ₁₀ - group, and the C ₆ -C ₁₀ aryl group, Z is carbon, silicon or germanium and, b = 1, 2, or 3, M = 4 group, in particular transition of Zr, Hf and Ti metal, O = oxygen, R ³ = C ₁ -C ₁₀ alkyl, C ₆ -C ₁₀ - an aryl group, where the alkyl group may be branched or unbranched, and may be substituted by an aryl group, the aryl group further A method for producing include a substituent), in the first step, the diastereomeric rac / meso mixture in the form of bridges, stereo azide metallocene dihalide, (Cp) (Cp ') M (X) ₂ expression the metallocene dihalide (having here, Cp = cyclopentadienyl, indenyl, fluorenyl radical, Cp '= one of the Cp groups which can be the same or different, Q = Cp and Cp 'between single-or multi-membered bridged (R ¹ -ZR ² ) b, where, R ¹ and R ² are the same or be different, each represent a hydrogen atom, C ₁ -C ₁₀ - alkyl, C ₆ -C ₁₀ - an aryl group, and Z is carbon, silicon or germanium and, b = 1, 2, or 3, M = 4 group, a transition metal, especially Zr and Hf, X = halogen, especially Cl ) is R ⁴ -M- (X) _n alkylating agents (where the formula, R ⁴ = C ₁ -C ₁₀ - alkyl, C ₁ -C ₁₀ - aryl, M = alkali metal or alkaline earth metal, preferably Mg, Na or Li, X = halogen, especially Cl is reacted with or Br, n = M of the oxidation number -1), then the reaction mixture or the isolated in the middle of the dialkyl metal rosen alcohol, aryl alcohol or HO-R ³ type of phenol (here, HO = hydroxyl group, R ³ = C ₁ -C ₁₀ - alkyl, C ₆ -C ₁₀ - an aryl group, where the alkyl group is a branched or unbranched, substituted by aryl may be, the present invention relates to a commercial aryl substituents wherein the further included) and the reaction.
