The cationic lanthanoid alkyl complexes (NCN)YR(THF)(+) (R = CH(2)SiMe(3)) bearing a NCN-ligand based on N,N'-bis(2,6-diisopropylphenyl)-benzamidine (AmH), N-[ 6-(2,4,6-triisopropyl-phenyl)-pyridin-2-yl]-(2,6-diisopropyl)aniline (ApH) or 1,3-bis(2,6-diisopropylphenyl)-2,2-dimethylguanidine (GuaH) combined with an excess of trialkyl aluminium compounds (AlR(3); R = Et, iso-Bu, n-Oct) are efficient catalysts for the highly controlled coordinative chain transfer polymerisation (CCTP) of ethylene, a catalysed version of the Aufbaureaktion. The aluminium terminated polyethylene (PE) can be oxidised to yield long chain alcohols which are the basis for a diverse polymer chemistry.
