Salt additives as activity boosters: a simple strategy to access heterometallic cooperativity in lactide polymerisation

Weronika Gruszka et al.

Summary: In this study, the concept of using inorganic salt additives to activate carbonyl groups towards organic addition reactions was translated to ring-opening polymerisation for the first time. Heterometallic ProPhenol catalysts were generated in situ, showing activity enhancements similar to pre-formed heterometallic complexes. Remarkably high activities were observed, with K/Mg and K/Ca combinations converting >85 eq. lactide in 5 s at room temperature.

Heterodinuclear Mg(II)M(II) (M=Cr, Mn, Fe, Co, Ni, Cu and Zn) Complexes for the Ring Opening Copolymerization of Carbon Dioxide/Epoxide and Anhydride/Epoxide

Natalia Reis et al.

Summary: This study systematically investigates a series of heterodinuclear Mg(II)M(II) complexes to identify the most effective metal combinations for the catalysed ring opening copolymerizations of carbon dioxide/epoxide and anhydride/epoxide. Mg(II)Co(II) and Mg(II)Fe(II) are found to be the fastest catalysts with high selectivity and control. Additionally, the transition metal heterodinuclear complexes exhibit synergic rate enhancements compared to the homodinuclear Mg(II)Mg(II) complex.

Perfectly Alternating Copolymerization of Cyclic Anhydrides and Epoxides with Yttrium β-Diketiminate Complexes

Yvonne Manjarrez et al.

Summary: Monometallic yttrium beta-diketiminate complexes are active and controlled catalysts for the ring-opening copolymerization of 1-butene oxide and phthalic anhydride. The strength and number of pendant neutral donors in the beta-diketiminate ligands, as well as the choice of initiating groups, affect the polymerization rates and side reactions. The presence of a cocatalyst enhances the activity of the catalysts, while lack of cocatalysts leads to competing homopolymerization. The tunability of rare earth metal complexes in this copolymerization process makes further research in this area promising.

Synergic Heterodinuclear Catalysts for the Ring-Opening Copolymerization (ROCOP) of Epoxides, Carbon Dioxide, and Anhydrides

Wilfred T. Diment et al.

Summary: The development of sustainable plastic materials using sustainable monomers and polymers that can be chemically recycled is a key goal of 21st century chemistry. However, designing efficient catalysts for these processes remains challenging due to issues such as low catalytic activities, high catalyst loading requirements, and the need for costly, toxic cocatalysts.

Multifunctional Catalysts for Ring-Opening Copolymerizations

Claire A. L. Lidston et al.

Summary: The ring-opening copolymerization (ROCOP) of epoxides with CO2 or cyclic anhydrides using multifunctional catalysts has been explored as a versatile route for synthesizing a wide range of polycarbonate and polyester copolymers. Covalently tethering the Lewis acid catalyst and cocatalyst together has been shown to increase both catalyst activity and selectivity in epoxide ROCOP. This review examines the development of multifunctional catalysts for copolymerization of epoxides with CO2, cyclic anhydrides, carbonyl sulfide (COS), and cyclic thioanhydrides, and evaluates how the mechanisms of these catalysts lead to improved activity and selectivity in ROCOP.

Chain end-group selectivity using an organometallic Al(iii)/K(i) ring-opening copolymerization catalyst delivers high molar mass, monodisperse polyesters

Wilfred T. Diment et al.

Summary: This article introduces a new catalyst for the ring-opening polymerization of epoxides and anhydrides, which shows high selectivity, fast reaction rates, and good molar mass control. The catalyst produces alpha,omega-hydroxyl telechelic polyesters with high molar masses and monomodal distributions. The high molar mass polyesters exhibit improved mechanical properties compared to medium molar mass samples. The catalyst can also be used to create triblock polyesters with high molar masses by enchainment of different monomers.

Trinuclear salphen-chromium(III)chloride complexes as catalysts for the alternating copolymerization of epoxides and cyclic anhydrides

Lei Cui et al.

Summary: This study demonstrates that trinuclear chromium complexes of salicylaldimine, in conjunction with a nucleophilic cocatalyst, are efficient catalysts for the copolymerization of epoxides and cyclic anhydrides, producing perfectly alternating polyesters. By investigating the distance between chromium species, it was found that trinuclear salphenCr(III)-complexes with distances of approximately 7.3 angstrom exhibit high catalytic activity even at low catalyst loadings. Additionally, in situ infrared spectroscopy studies suggest that the activation energy of the trinuclear Cr(III)-salphen catalyst is lower than that of the corresponding mononuclear catalyst due to an intramolecular synergistic effect among the metal atoms.

Alkali Metal Carboxylates: Simple and Versatile Initiators for RingOpening Alternating Copolymerization of Cyclic Anhydrides/Epoxides

Chong-Min Chen et al.

Summary: In this study, the ring-opening alternating copolymerization of cyclic anhydride and epoxide was thoroughly investigated using alkali metal carboxylates as initiators. The coordination effects of epoxide on the alkali metal carboxylate were verified using FT-IR spectroscopy and DFT calculations. Alkali metal carboxylates were found to effectively catalyze the copolymerization of cyclic anhydride and epoxide, leading to the synthesis of polyesters with alternating structures. The use of potassium acetate was particularly noteworthy as it allowed for the copolymerization of different cyclic anhydrides and epoxides, including the high molar feed ratio synthesis of poly(PA-alt-PO) with a molecular weight exceeding 100 kDa.

Polymers from Sugars and Cyclic Anhydrides: Ring-Opening Copolymerization of a D-Xylose Anhydrosugar Oxetane

Thomas M. McGuire et al.

Summary: In this study, a D-xylose 3,5-anhydrosugar derivative was used as an oxetane co-monomer in the ring-opening copolymerization (ROCOP) with cyclic anhydrides to synthesize a family of seven novel sugar-derived polyesters with up to 100% renewable content. These polyesters are thermally robust and exhibit a broad range of glass-transition temperatures, allowing for further postpolymerization functionalization. The living character of the ROCOP process was also utilized to synthesize block copolymers through sequential co-monomer addition experiments.
