ABSTRACT:
Novel α-diimine metal complexes, particularly iron complexes, having a phenyl sulfidyl or substituted phenyl sulfidyl metal complexing group are disclosed. The α-diimine metal complexes having a phenyl sulfidyl or substituted phenyl sulfidyl metal complexing group are produced by forming one of the α-diimine metal complex imine bonds in the presence of a metal salt or an α-acylimine metal complex. The α-diimine metal complexes having phenyl sulfidyl or substituted phenyl sulfidyl metal complexing group are useful for polymerizing or oligomerizing olefins.
