| Summary: |
Functionalized aluminium alkyls enable an effective coordinative chain transfer polymerization with selective chain initiation by the functionalized alkyl. (ω-aminoalkyl)diisobutyl aluminum reagents (twelve examples studied) obtained by hydroalumination of α-amino-ω-enes with diisobutyl aluminum hydride promote the stereoselective catalytic chain growth of butadiene on aluminum in presence of Nd(versatate)3, Cp*2Nd(allyl) or Cp*2Gd(allyl) precatalysts and [PhNMe2H+]/[B(C6F5)4-]. Carbazolyl- and indolyl- aluminum reagents result in efficient molecular weight control and chain initiation by the aminoalkyl rather than isobutyl substitutent bound to aluminum. As evidenced for (3-(9H-carbazol-9-yl)propyl) initiated polybutadiene (PBD) inter alia by deuterium quenching studies, polymer chain transfer by β-hydride transfer is negligible in comparison to back-transfer to aluminum.
