Abstract:
Both symmetric and nonsymmetric bis(aryl)acenaphthenequinonediimine ligands, featured by substituents
in meta-positions of the aryl rings, have been applied for the first time as ancillary ligands for the palladiumcatalyzed
CO/vinyl arene copolymerization. The nature and the number of substituents affect both the
productivity and the molecular weight of the synthesized copolymers. Palladium complexes containing
the nonsymmetric ligands are the most efficient catalysts reported so far for the synthesis of atactic
polyketones.
