The Lanthanide Ziegler−Natta Model:  Aluminum-Mediated Chain Transfer

, 2016
C2-symmetric tetraalkylaluminate complexes rac-[Me2Si(2-Me-C9H5)2]Y(μ-R)2AlR2 and terminal alkyl complexes rac-[Me2Si(2-Me-C9H5)2]YR(THF) (R = Me, Et, iBu) are quantitatively formed via a special silylamide elimination reaction.

Mimicking Ziegler-Natta catalysts in homogeneous phase, Part 1 - C2-symmetric octahedral Zr(IV) complexes with tetradentate [ONNO]-type ligands

, 2001
Propene polymn. was carried out in the presence of 2 of the title Zr complexes, giving isotactic site-controlled or weakly syndiotactic chain-end-controlled polymers via highly regioselective 1,2 primary monomer insertion. The two catalysts are believed
