Abstract
Reaction between M(C6F5)(3) (M = B, Al) and AlR3 in hydrocarbons leads to f acile aryl/alkyl group exchange and formation of aluminum dimers, while rea ction of(perfluoroaryl)boranes B(C6F5)(3) and B(C12F9)(3) with AlR3 (R = Me , Et, octyl) or GaMe3 in ether solvents produces alumocenium or gallocenium berates. Neutral aluminum dimers and cationic alumocenium species have bee n found to be very effective as catalyst activators in ethylene/1-octene co polymerization.
