摘要

Some manganese and nickel pyridyl-imine complexes are synthesized

characterized and used in the polymerization of butadiene

obtaining predominantly 1

2 and exclusively cis-1

4 polymers

respectively.It should be underlined that practically nothing has ever been reported in the literature on manganese-based catalysts for the stereospecific polymerization of conjugated dienes.

Abstract

Some novel manganese and nickel complexes were synthesized by reacting manganese(II) dichloride and nickel(II) dichloride with pyridyl-imine ligands differing in the nature of the substituents at the imino nitrogen atom. All the complexes were characterized by analytical and infrared data: for some of them single crystals were obtained

and their molecular structure was determined by X-ray diffraction. The complexes were used in association with methylaluminoxane (MAO) for the polymerization of 1

3-butadiene obtaining active and selective catalysts giving predominantly 1

2 polybutadiene in case of manganese catalysts and exclusively

cis

-1

4 polybutadiene in case of nickel catalysts.
