Understanding the role of aluminum-based activators in single site iron catalysts for ethylene oligomerization
نویسندگان
چکیده
In a combined experimental and theoretical study the activation process of a single site ethylene oligomerization catalyst with aluminum based activators has been studied. The results put forward a plausible deactivation reaction path of the catalyst for trimethylaluminum, while for methylaluminoxane and a novel phenoxyaluminum-based activator the experimental catalyst’s activity correlates with the energy barrier for the ethylene insertion.

Intelligent catalysts for ethylene oligomerization and polymerization
EEthylene polymerization catalysts became available in an enormous variety. The challenge in this research is to find catalysts that are able to connect ethylene molecules in such a way that not only linear chains are produced but variations like branched materials that possess very interesting mechanical properties like linear low density polyethylene (LLDPE). In this contribution, three diffe...
متن کاملHalogen substituted iron(III) di(imino)pyridine complexes as catalysts for 1- pentene/1-hexene co-oligomerization reactions
Nine different bis(arylimino)pyridine complexes of Fe(III) with different halide substituents (F, Cl, Br, I) at different positions of the iminophenyl group of the ligand have been synthesized, characterized and applied for homogeneous 1-pentene and 1-hexene oligomerization and co-oligomerization reactions after activation with methylaluminoxane (MAO). The best activity in 1-hexene oligomerizat...
متن کاملAlternative aluminum-based cocatalysts for the iron-catalyzed oligomerization of ethylene.
Multinuclear aluminum cocatalysts have been obtained by the reaction of various phenols, alcohols or diols with trimethylaluminum and were used in situ or as isolated, well-defined species, for the activation of an iron(ii) or an iron(iii) pre-catalyst for the oligomerization of ethylene. The best cocatalyst candidate involves 2,2'-biphenol () in a /AlMe3 ratio of 2/3.
متن کاملHomogeneous and heterogeneous oligomerization reactions of olefins with unbridged metallocene catalysts
1-Pentene, respectively 1-hexene, were reacted with 13 homogeneous metallocene catalysts to give linear oligomerization products, predominantly dimers, with selectivities above 90%. The product distributions of the codimerization reactions of 1-pentene with 1-hexene reflected a binomial behaviour. Therefore, the ratio for dimers is 1:2:1 (C10:C11:C12) while the trimers (pentadecenes up to octad...
متن کاملDissymmetric dinuclear transition metal complexes as dual site catalysts for the polymerization of ethylene
A series of dissymmetric dinuclear complexes were synthesized, as dual site catalysts in ethylene polymerization, by coupling the allylated a-diimine complexes of the metals Ti, Zr, V, Ni and Pd with the ansa-zirconocene complex [C5H4-SiH(Me)-C5H4]ZrCl2 possessing a hydride silane moiety. The different stages of syntheses included the formation of bis(cyclopentadienide)methyl silane which was u...
