Abstract

original image

Exzellenter Aktivator: Die lebende cis-1,4-Polymerisation und -Copolymerisation von Isopren und Butadien gelang erstmals mithilfe einer in situ gebildeten kationischen Alkylyttrium-Spezies (siehe Schema). Ein verwandter kationischer Alkyllutetium-Komplex, der als definiertes Strukturmodell für die katalytisch aktive Spezies dient, wurde isoliert und strukturell charakterisiert.
