The new 1,3-disiloxo-bridged dichloro zirconocene [{(η5-C5H3)2-μ,μ-1,3-(Me2SiOSiMe2)2}- ZrCl2] (2) has been synthesized and fully characterized. Complex 2, combined with MAO, polymerizes propene and 1-hexene with high 1,2-regioselectivity, yielding oligomers containing vinylidene end groups produced via a β-hydrogen elimination reaction.

Abstract
The new 1,3-disiloxo-bridged dichloro zirconocene [{(η5-C5H3)2-μ,μ-1,3-(Me2SiOSiMe2)2}- ZrCl2] (2) has been synthesized and fully characterized. Complex 2, combined with MAO, polymerizes propene and 1-hexene with high 1,2-regioselectivity, yielding oligomers containing vinylidene end groups produced via a β-hydrogen elimination reaction.File in questo prodotto:
