Selective Formation of Ethyl- and/or Propyl-branched Oligoethylene Using Double-decker-type Dinuclear Fe Complexes as the Catalyst
Dinuclear Co and Fe complexes with a double-decker structure supported by macrocyclic ligands having two bis-(imino)pyridine and xanthene groups were synthesized. The dinuclear Fe complex catalyzes ethylene oligomerization in the presence of MMAO or Me3Al to give oligoethylene with ethyl and/or propyl branches due to cooperative interaction of two Fe centers.
