Abstract
Self-help groups: The aluminatopyrrolyl complexes [{η5-2,3, 4,5-Me4C4N(AlClMe2)}2Cr] and [{η5-2,3,4,5-Me4C4N(AlClMe 2)CrMe(μ-NPh)2AlMe2}{Me3Al(thf)}] self-activate to give single-site ethylene polymerization catalysts. The closely related dinuclear chromium(II) complex [{η5- 2,3,4,5-Me4C4N(AlClMe2)Cr}2(μ-Me) 2] (see picture) is a highly active self-activating ethylene trimerization catalyst. © 2009 Wiley-VCH Verlag GmbH & Co.
