One-component air-stable iron catalysts for the ROCOP of epoxides and cyclic anhydrides
Bio-sourced polyesters have been synthesized by ring-opening copolymerization reaction of epoxides and cyclicanhydrides using air-stable one-component heteroscorpionate Fe(III)-halide catalysts. Alternating polyestersfrom renewable resources such as limonene oxide, endo/exo-carvone oxides and succin...

| Sumario: | Bio-sourced polyesters have been synthesized by ring-opening copolymerization reaction of epoxides and cyclicanhydrides using air-stable one-component heteroscorpionate Fe(III)-halide catalysts. Alternating polyestersfrom renewable resources such as limonene oxide, endo/exo-carvone oxides and succinic and citraconic anhydrides,have been obtained with reasonable molecular weight, narrow dispersity, and high percentage of esterlinkages under air conditions. There are few examples of air-stable “one-component” metal-based catalysts in theliterature, tending to rely on external additives, and the results hereby reported provide hope that air-stablefriendly metals complexes can be effective systems in future sustainable polymerization research. The microstructureand thermal properties of the polyesters synthesized have been investigated and discussed, and for theamorphous copolymers, the Tg values have shown values from 17.5 ?C to 128.5 ?C. |
