Abstract

Summary: Rac‐[CH 2(2,4‐di‐tert‐butyl‐cyclopentadienyl)2]ZrCl 2 (1), rac‐[CH 2(3‐tert‐butyl‐4,5,6,7‐tetrahydroindenyl)2]ZrCl 2 (2), rac‐[CH 2(3‐isopropyl‐4,5,6,7‐tetrahydroindenyl)2]ZrCl 2 (3), and rac‐[CH 2(3‐methyl‐4,5,6,7‐tetrahydroindenyl)2]ZrCl 2 (4) were synthesized and characterized by 1 H NMR analysis. These C 2 symmetric ansa‐zirconocenes, activated with methylaluminoxane (MAO), were able to promote copolymerization of ethene and 1,3‐butadiene. The structures of the copolymers are strongly influenced by zirconocene utilized as catalytic precursor. Depending on the reaction conditions polyethenes containing cyclopropane and cyclopentane rings, or 1,1‐ 1,3‐butadiene inserted constitutional units, were obtained. Structures of the synthesized catalytic precursors. magnified imageStructures of the synthesized catalytic precursors.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
