High molecular weight PE elastomers through 4,4-difluorobenzhydryl substitution in symmetrical α-diimino-nickel ethylene polymerization catalysts

“…By comparison, the structure of the free ligand, L3, shows a E,E-strans conguration with the bulky ortho-substituents on each Naryl ring adopting an anti conformer; such a transoid disposition of the imine nitrogens in 1,4-diazabutadienes is commonplace. 15 The C-N imine bond lengths (N1-C3 1.276(3) A, N2-C4 1.270(3) A) are nonetheless similar to that seen in complexes Ni1 (N1-C3 1.288(13) A, N2-C4 1.323(12) A) and Ni5 (N1-C3 1.291(12) A, N2-C4 1.286(12) A). The 4,4-diuorobenzhydryl substituents in each of the three structures show no unusual features.…”
