Abstract
Methods for making α-diimine metal complexes are described. The methods comprise forming an α-diimine metal complex imine bond in the presence of a metal salt or an α-acylimine metal complex. The method is particularly using for the production of α-diimine metal complexes having two different α-diimine nitrogen groups. The α-diimine metal complexes are useful for polymerizing or oligomerizing olefins.
