We report here a ligand-free cobalt-based catalyst for the alkoxycarbonylation of chloroacetates to dialkyl malonates, which are important industrial intermediates. This catalyst uses an extremely inexpensive precursor, CoCO3, with a very low catalyst loading (0.5 mol%) to achieve product yields of up to 99% with nearly 100% chemoselectivity. Solvents and previously essential phase transfer agents are not needed. Most importantly, the catalyst can be easily recycled without losing its activity and selectivity. Over 95% product yield was achieved even after 8 recycles. The feasibility of this system was demonstrated through 14 examples of the alkoxycarbonylation reaction.

Specifically, PDDF displays significantly lower oxygen and carbon dioxide permeability than commercial poly(butylene adipate-co-terephthalate) (PBAT) and linear low-density polyethylene , alongside a markedly higher modulus (by ≈3 ×) and reduced water vapor transmission rate compared to PBAT. This superior performance is attributed to the inherently rigid, polar, H-bonding furan rings that enhance chain interaction, packing and crystallinity and thus reduce free volume impeding gas diffusion, while the long hydrophobic dodecylene segments inhibit water permeation. Furthermore, PDDF can be recycled back to its cyclic monomer by base-catalyzed depolymerization or diester and diol monomers by simple methanolysis.
