Abstract
Trimethylaluminum reacts with [CPh3][B(C6F5)(4)] at elevated temperatures t o give a mixture of AlMe3-x(C6F5)x compounds, depending on the Al/B ratio. AlBu3i reacts significantly faster under beta-hydride abstraction. The Al-C 6F5 species rapidly react with Cp2ZrMe2 or [Cp2ZrMe](+) under C6F5 transfer to give poorly active Cp2ZrMe(C6F5); this reaction may have implications f or the deactivation of Cp2ZrMe2/AlR3/[CPh3][B(C6F5)(4)] olefin polymerizati on catalysts.
