• Propylene bulk phase oligomerization with bisiminepyridine iron complexes in a calorimeter: mechanistic investigation of 1,2 versus 2,1 propylene insertion

  Iron(II) complexes were synthesized with bisiminepyridine ligands of low steric demand. Activation with modified-methylaluminoxane (25 mol.% isobutyl groups) generated very active catalysts for propylene oligomerization. The oligomerizations were carried out in liquid propylene in a heat flow calorimeter. The oligomers were separated by preparative gas chromatography and the dimers and trimers analyzed using analytical gas chromatography, H-1-NMR- and C-13-NMR-spectroscopy. With knowledge of the dimer and trimer structure, we were able to establish a mechanistic pathway for propylene insertion and obtained knowledge about the iron alkyl species involved. Analysis of the various dimers formed allowed us to determine the percentage of 1,2 versus 2,1 propylene insertions. Considering the same iron alkyl species with ligands of different steric demand, a change in the probabilities for 1,2 versus 2,1 propylene insertions can be observed. With this knowledge, the catalyst behavior for ligands of varying steric demand can be predicted. (C) 2003 Elsevier B.V. All rights reserved.

  The synthesis of new iron(Pi) diiminopyridine complexes and their heterogenization to give highly active ethene polymerization catalysts is described. The ligands are characterized by (HNMR)-H-1, (CNMR)-C-13 spectroscopy and GC/MS. The complexes are paramagnetic and were characterized by elemental analyses and mass spectrometry. The complexes were activated and heterogenized with a cocatalyst consisting of partially hydrolyzed trimethylaluminum (PHT) on silica gel and were used for ethene polymerization.The polymerization results and the polymer properties are presented. The influence of the catalyst structure, hydrogen and 1-hexene on the polymerization behavior is discussed. (C) 2002 Elsevier Science B.V. All rights reserved.
• New iron-based bis(imino)pyridine and acetyliminopyridine complexes as single-site catalysts for the oligomerization of ethylene

  New iron-based bis(imino)pyridine complexes 6, 7 and the acetyliminopyridine complex 8a are active catalysts together with the co-catalyst MAO for the oligomerization of ethylene. The ligands 1-4 with electron donating methoxy- and electron withdrawing trifluoromethyl-substituents react with FeCl2 (thf)(2) to the Fe(II) complexes 6-8a. Especially p-methoxy substituents in 6b increase the selectivity in the production of alpha-olefins. The distribution of oligomers obtained in the catalyzed ethylene oligomerization with 5-8a follows Schulz-Flory rules for oligomers >C-4. The probability of chain propagation ot is increased by lowering the reaction temperature, while higher pressure of the ethylene gas in the reaction has nearly no effect on the ce-values.
