Ruthenium( ii ) PNN complexes depolymerize many polyesters into diols and polycarbonates into glycols plus methanol via hydrogenation. Notably, polyesters with two methylene units between ester linkages depolymerize to carboxylic acids rather than diols. This methodology represents a new approach fo...

Summary:Ruthenium( ii ) PNN complexes depolymerize many polyesters into diols and polycarbonates into glycols plus methanol via hydrogenation. Notably, polyesters with two methylene units between ester linkages depolymerize to carboxylic acids rather than diols. This methodology represents a new approach for producing useful chemicals from waste plastics. Ruthenium( ii ) PNN catalysts hydrogenatively depolymerize polyesters and polycarbonates, converting waste plastics into value-added chemicals.
