Copolymerization of Aziridines and Carbon Monoxide Catalyzed by a Heterodinuclear Organopalladinum–Cobalt Complex

Heterodinuclear organopalladium–cobalt complex having a 2,2ʹ-bipyridine ligand (bpy)AcPd–Co(CO)4 catalyzes copolymerization of unsubstituted and both C- and N-monosubstituted aziridines, such as aziridine, 2-methylaziridine, and N-ethylaziridiene, and CO (3–6 MPa) in THF at 100 °C for 6 h.
