Nickel-catalyzed carboannulation reaction of o-bromobenzyl zinc bromide with unsaturated compounds

(Chemical Equation Presented) A number of indenes have been prepared in good yields by treating o-bromobenzyl zinc bromide 1 with various terminal and internal alkynes in the presence of a nickel catalyst. The nickel-catalyzed carboannulation reaction was successfully extended to the synthesis of indane derivatives by reaction of 1 with acrylates and styrene.

Unbridged metallocene dichloride complexes with mono-substituted indenyl ligands and their application for the polymerization of propene

The synthesis of unbridged metallocene dichloride complexes of the type Ind′2ZrCl2 (Ind′ = 2-alkyl- or arylalkyl-substituted indenyl) is described. The complexes are characterized by 1H- and 13C-NMR spectroscopy and mass spectrometry. After activation with methylalumoxane these complexes can be used for propene polymerization; they produce block copolymers consisting of alternating isotactic and atactic blocks. The polymerization results and the polymer properties are presented. The influence of the catalyst structure on the polymerization behaviour is discussed.

Synthesis and characterization of new bis(2-R-indenyl) zirconium dichloride complexes for the olefin polymerization

A series of 2-alkylindene(2-RInd; R=Me, i-Pr, n-Bu, Bzl, Cy, t-Bu) were prepared by nucleophilic addition of the corresponding alkyl anions to 2-indanone in the presence (or absence) of LaCl3. With these 2-alkylindenes, bis(2-alkylindenyl)zirconium dichloride complexes were synthesized to investigate the effects of alkyl substituents at 2-position of indene on the rotational conversion rate between rotamers (racemic and meso) and the catalytic activities toward olefin polymerization. Analysis of NMR spectra could line up the electron donating abilities and steric bulkiness of alkyl substituents in order and variable temperature NMR analysis (from 298 to 193 K) proved that these alkyls could not freeze free rotation of indenyl ligands. These complexes showed catalytic activities toward ethylene and propylene polymerization and the variation of catalytic activities(PE, Me〉Cy〉i-Pr〉Bzl〉n-Bu; PP, Me〉n-Bu〉i-Pr〉Cy〉Bzl), molecular weights(PE, n-Bu〉Cy〉i-Pr〉Me〉Bzl; PP, n-Bu〉Me〉Cy〉i-Pr〉Bzl), and polydispersities(PE, 2.80-5.05; PP, 2.23-3.30) were rationalized with steric, electronic, and structural factors. Steric bulkiness of substituents played an important role in the propylene polymerization but relative importance of these factors were different in the ethylene polymerization.

Indenyl compounds and catalyst components for the polymerization of olefins

The invention relates to an indenyl compound of the general formula in which the symbols have the following meanings: Ind: an indenyl group R': a substituent, other than hydrogen, to the Ind group, Cp: a cyclopentadienyl group M: a transition metal from group 3, 4, 5 or 6 of the Periodic System of Elements Q: a ligand to M and k is an integer linked to the valence of M. The invention is characterized in that the R' group is bound to the Ind group at the 2-position. The indenyl compound is a catalyst component for the polymerization of olefins. The invention also relates to polymers obtainable with such indenyl compounds.
