Definitions

  • the quantity employed is sufficient to provide 0.1 to 20,000 atoms, preferably 1 to 2000 atoms of aluminium or boron per transition metal atom of the transition metal complex.
  • the complexes utilised in the present invention can if desired comprise more than one of the above-mentioned group 3-10 transition metal, group 3 main group metal, lanthanide or actinide complexes.
  • the complexes of the present invention can be unsupported or supported on a support material, for example, silica, silica/alumina, magnesium chloride, zeolites, alumina or zirconia, or on a polymer or prepolymer, for example polyethylene, polystyrene, or poly(aminostyrene), or on another heterogeneous catalyst.
  • a support material for example, silica, silica/alumina, magnesium chloride, zeolites, alumina or zirconia, or on a polymer or prepolymer, for example polyethylene, polystyrene, or poly(aminostyrene), or on another heterogeneous catalyst.
  • both the complexes and activators are co-supported on the support material, polymer or prepolymer.
  • the chain growth reaction illustrated in equation 3 may utilize a neat zinc alkyl medium or may utilize a hydrocarbon solvent diluent such as toluene or heptane.
  • a hydrocarbon solvent diluent such as toluene or heptane.
  • higher (C 3 -C 20 + alpha-olefins such as 1 -octene may be used as a solvent or co-solvent.
  • Reaction temperatures may vary from approximately room temperature 20°C to 150°C.
  • Pressures of ethylene may be varied from about 15 psig to about 1500 psig.
  • C 2 to C 0 + alpha-olefins can be recovered from alkylzinc compounds by catalytic displacement with, for example, a Ni catalyst, using ethylene and/or other alpha olefins as the displacing olefin.
  • the chain growth products can be oxidized to zinc alkyl peroxide intermediates, oxidized and hydrolyzed using known procedures to produce linear primary alcohols, or used in known procedures to make other specialty materials.
  • EXAMPLES Manipulation of complexes, zinc alkyls, and optional activators, as well as the assembly and disassembly of reactors were conducted under a nitrogen atmosphere. Ethylene was polymer grade, used without purification. 2,6-bis[l-(2,6- diisopropylphenyl)imino)ethyl]pyridine iron(II) chloride and 2,6-bis[l-(2,6- diisopropylphenyl)imino)ethyl]pyridine cobalt(II) chloride were prepared according to the established procedure described in WO 99/12981.
  • Bis(cyclopentadienyl)zirconium dichloride, bis(pentamethylcyclopentadienyl)zirconium dichloride, nickel(II) acetylacetonate, trimethyl aluminium (2M in toluene), dodecane (anhydrous), cyclohexane (anhydrous), and nonane (anhydrous) were obtained from Aldrich. Undecane was obtained from Aldrich and distilled over CaH 2 prior to use.
  • Diethyl zinc solution was obtained from Acros (0.87M in toluene) or Aldrich (1.1M in toluene or heptane), rac- Ethylenebis(indenyl)zirconium(IN) dichloride and nickel naphthenate was obtained from Strem Chemical. 1-hexene (98.07% pure) from BP was used.

  • EXAMPLE 9 Catalysed chain growth using a cobalt pyridylbisimine catalyst
  • 2,6-bis[l-((2,6- diisopropylphenyl)imino)ethyl]pyridine cobalt(II) chloride was studied (5 ⁇ mol Co, 100 eq MAO, 1 bar ethylene, 50 ml toluene, 30 min, RT).
  • EXAMPLE 11 Catalysed chain growth followed by chain displacement of ⁇ -olefins from dialkylzinc.
  • a mixture of dialkylzinc was produced in a reaction similar to example 1 (2 ⁇ mol Fel, 1750 eq ZnEt 2 , 100 eq MAO, 1 bar ethylene, 50 ml toluene, 8 min, RT). After 8 min reaction the contents of the Schlenk flask were transferred into another Schlenk containing dry silica. After 15 min stirring the toluene solution was filtered into a Schlenk containing a solution of Ni(acac) 2 (0.35 mmol) in 10 ml toluene under 1 bar ethylene pressure. The reaction mixture was hydrolysed after 30 min by addition of 50 ml 2M HCl.
  • the samples were hydrolysed and hexene and hexane analysed by GC.
  • the amount of hexane corresponds to the amount of hexyl-zinc moieties formed from the displacement of ethylene from the diethylzinc.
  • the extent of displacement is provided in Table 2.
