- •
Dinuclear salen-co(III) complexes were synthesized and applied in CO2 and epoxides copolymerization.
- •
The dinuclear system showed very high activity with a turn over frequency (TOF) of 406 h−1 at [PO]/[Cat] = 20,000.
- •
The dinuclear system offered the highest molecular weight (Mn = 200,000) among reported dinuclear catalysts heretofore.
