Definitions
- the present invention relates to a general synthetic method for the preparation of previously unknown zirconocenes and hafnocenes which carry a boron substituent directly on the cyclopentadienyl ligand. These compounds find a new use in the polymerization of olefins with cocatalysis of aluminum alkyl compounds.
- a large number of metallocene-based catalyst systems are known in the literature. Common to all is the need for a cocatalyst that converts the metallocene into an active form that is able to polymerize olefins. A zirconium cation is generated according to the generally accepted concept.
- MAO-free systems are based on the use of dialkyl metallocenes with "cationization reagents". Only "ligand-free” systems show good polymerization properties (R. F. Jordan, Adv. Organomet. Chem. 1991, 32, 325). Common cationization reagents are ammonium compounds (HW Turner, Eur. Pat. Appl.
- Borylated zirconocenes and hafnocenes are not described in the literature. Their synthesis does not succeed according to common methods of metallocene synthesis (DJ Cardin, MF Läppert, CL Raston, Chemistry of Organo-Zirconium and - Hafnium Compounds, Ellis Horwood Ltd., Chichester, 1986), because in the treatment of borylated cyclopentadienes with bases or metalation reagents Breakage of the BC bond occurs.
- the corresponding borylated zirconocenes and hafnocenes can be synthesized from simultaneously borylated and silylated precursors. There is no systematic access to the borylated and silylated cyclopentadienes.
- Alkoxyboranes or amine adducts of alkylboranes can be introduced via metalated precursors (BM Mikhailov, TK Baryshnikova, VS
- Halogen boranes are accessible via Si-B exchange and alkoxy boranes via Sn-B exchange (P. Jutzi, A. Seufert, J.
- Halogen boranes with other radicals obtained a Si-B-cyclopentadiene, which by
- cyclopentadienyl ligands can also be attached cyclopentadienyl ligands such as indenyl, tetrahydroindenyl, which in turn can carry substituents such as alkyl, aryl, benzyl radicals or heteroatoms such as halogens (F, Cl, Br, I), silicon and germanium.
- substituents such as alkyl, aryl, benzyl radicals or heteroatoms such as halogens (F, Cl, Br, I), silicon and germanium.
- the other cyclopentadienyl ligand can be the same as the first, but can also be boron-free and carry the same or different substituents as listed above.
- L 'can be another cyclopentadienyl ligand like the first, i.e. H. carry the same or different substituents, but it can also be boron-free.
- R 1 to R 4 can be different from R 5 to R s .
- R 4 and R 8 can also contain methyl, ethyl, allyl, phenyl, aryl, benzyl radicals and heteroatoms such as halogens (F, Cl , Br, I), silicon, germanium. If the bridge consists of only one boron, then R 1 to R 4 are equal to R 5 to R 8 .
- the substituent L on the boron of the cyclopentadienyl ligand or on the boron of the bridge can be alkyl, aryl, benzyl, fluorinated alkyl or aryl, halogens (F, Cl, Br, I), OH, alkoxy , where the residues can form part of a cycle.
- the substituents X on the transition metal can be a halogen or nitrogen.
- the same metallocene complexes can also be obtained by an alternative synthetic route.
- boron-substituted cyclopentadiene compounds with weakly nucleophilic bases such as. B. lithium bis (trimethylsilyl) amide deprotonated and then converted by transmetallation into the corresponding metallocenes.
- weakly nucleophilic bases such as. B. lithium bis (trimethylsilyl) amide deprotonated and then converted by transmetallation into the corresponding metallocenes.
- the corresponding borylated zirconocenes and hafnocenes can be synthesized from all borylated precursors. In these cases, the precursors no longer necessarily have to be silylated. In the case of zirconocenes and hafnocenes with a one-member boron bridge, complexes are also accessible which have differently substituted cyclopentadienyl rings.
- Zirconocenes and hafnocenes bridged differently can also be obtained by mild thermolysis of bisborylated zirconocene and hafnocene derivatives with alkoxy radicals on the boron:
- the R 'radicals can be any alkyl or aryl groups.
- zirconocenes and hafnocenes which can be prepared in this way are to be used as catalyst components in olefin polymerization, with an activity which is up to a factor of 10 greater than that of the parent compound Cp 2 ZrCl 2 of zirconocenes.
- the solid still contains 10-20% of the bis ( ⁇ 5 - (3-methyl-2,3-dihydro-benzoboroyl) cyclopentadienyl) (dichloro) zirconium (IV).
- the tan residue is recrystallized from a little hexane and the tan residue is dried again in an oil pump vacuum for 24 h. This process can be repeated several times, but it is never possible to remove all (chlorine) (trimethyl) tin.
- the bis (pentafluorophenyl) (3-trimethylsilylcyclopentadienyl) borane is also always contaminated by higher molecular weight compounds. Due to its temperature sensitivity, distillation is not possible. Yield: approx. 80 - 90% (NMR)
- a suspension of 4.02 g (12.2 mmol) of [bis (indenyl) (phenyl) borane] diüthium in 150 ml of toluene and 30 ml of diethyl ether is cooled to -78 ° C. and mixed with 2.85 g (12.2 mmol) of zirconium tetrachloride.
- the mixture is allowed to warm to room temperature in a cold bath and a brown-red suspension is obtained after 30 hours. After filtering off insolubles, the dark red filtrate is stored at -20 ° C for three days, whereby 908 mg (14%) of an orange-red powder can be isolated.
- the remaining solution is evaporated to dryness in an oil pump vacuum, and 2.45 g of the zirconocene dichloride (contaminated crude product) can be isolated as a red-brown powder.
- a suspension of 8.53 g (22.8 mmol) of the dilithium salt in 150 ml of toluene and 50 ml of diethyl ether is cooled to -78 ° C. and 5.31 g (22.8 mmol) of zirconium tetrachloride are added.
- the mixture is allowed to warm to room temperature in a cold bath and an orange suspension is obtained after 30 hours.
- the orange-colored filtrate is concentrated to dryness in an oil pump vacuum and 12.9 g (95%) of the zirconocene dichloride is obtained as a crude product as a yellow powder.
- a diastereomer can be significantly enriched by extraction with pentane:
