New C 2 v-and Chiral C 2-Symmetric Olefin Polymerization Catalysts Based on Nickel (II) and Palladium (II) Diimine Complexes Bearing 2, 6-Diphenyl Aniline …
The present contribution reports on a series of new diimine ligands and complexes bearing 2, 6-diphenyl-modified aniline moieties. The influence of different substituents on the complex structures as well as on their polymerization behavior was investigated. Interestingly the racemic complex 4c adopts a chiral, C 2-symmetric coordination geometry, due to a distinct repulsion of the tert-butyl fragments.
