摘要：

(Chemical Equation Presented) Switchable catalytic activity, from nonselective ethylene oligomerization to trimerization and even polymerization, is shown by 1, depending on the alkyl aluminum compound with which it is activated. AlMe3 or iBu2AlCl resulted in highly active single-component polymerization catalysts (see scheme; R = Me, PE = polyethylene), the activity of which can be switched or inhibited by the presence of an additional alkyl aluminum compound. © 2008 Wiley-VCH Verlag GmbH & Co.
