Abstract:
Addition of 1-hexene to methylalumoxane-activated catalyst systems based on rac-Me2Si(ind)2ZrMe2 causes, concurrent with polyhexene formation and diminution of the otherwise prevalent cation [rac-Me2Si(ind)2Zr(μ-Me)2AlMe2]+, formation of a hitherto unobserved species [rac-Me2Si(ind)2Zr(μ-R)(μ-Me)AlMe2]+, where R is a Zr-bound polyhexyl chain. As hexene is increasingly consumed, this cation decays, mainly back to [rac-Me2Si(ind)2Zr(μ-Me)2AlMe2]+ and, in part, to some species containing a Zr-bound allylic chain end.
