                                    Reaction of equimolar quantities of PdMe2(Me2NCH2CH2NMe2) and B(C6F5)(3) in the presence of ethylene results in the formation of [PdMe(C2H4)(Me2NCH2CH2NMe2)](+)[BMe(C6F5)(3)](-); the latter catalyzes the oligomerization of ethylene to highly branched products, which are apparently formed via both reversible beta-elimination-reinsertion processes and the incorporation of short chain oligomeric products.
