摘要
The new 1,3-disiloxo-bridged dichloro zirconocene [{(eta(5)-C5H3)(2)-mu,mu-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 beta-hydrogen elimination reaction.
