Cooperative Heterometallic Catalysts for Lactide Ring-Opening Polymerization: Combining Aluminum with Divalent Metals

Anand J. Gaston et al.

Summary: This study describes four heterobimetallic (salen)Al catalysts and demonstrates that cooperative Al/Mg and Al/Zn combinations can significantly enhance catalyst activity, compared to mono-Al analogues. In contrast, Al/Li and Al/Ca combinations were found to inhibit the polymerization rate. Kinetic and computational studies suggest that chloride bridging in close intermetallic proximity enhances initiation and increases available monomer coordination sites in Al/Mg and Al/Zn complexes. Additionally, ab initio molecular dynamics calculations were utilized to investigate catalyst flexibility and reveal that ligand strain and molecular rigidity can enhance the performance of heterometallic catalysts.

Advances in heterometallic ring-opening (co)polymerisation catalysis

Weronika Gruszka et al.

Summary: Improving catalyst performance for ring-opening (co)polymerisation (RO(CO)P) reactions by using heterometallic cooperativity is a promising yet underexplored strategy. Here the authors review advances in heterometallic RO(CO)P catalyst design, highlighting the overarching structure-activity trends and reactivity patterns to inform future catalyst design.

Efficient ternary catalyst system for the copolymerization of lactide, epoxides and CO2: new insights into the cooperative mechanism

Xiang Li et al.

Summary: The study focused on a new homogeneous ternary catalyst system (TCS III) which showed higher activity compared to the previous TCS I and remained active even under diluted conditions. Detailed analysis of the microstructure of the resulting copolymer revealed that SalenCo(III)-DFTP's difference in X-axial ligands provides it with unique catalytic properties.

Copolymerization of lactide, epoxides and carbon dioxide: a highly efficient heterogeneous ternary catalyst system

Xiang Li et al.

Summary: A novel heterogeneous ternary catalyst system (TCS) comprising of SalenCo(III), zinc glutarate (ZnGA) and PPNCl has been proposed, demonstrating intermolecular cooperation between cobalt and zinc to form multiblock copolymers. The TCS shows high activity and selectivity in the controlled copolymerization of mixed monomers.
