摘要 | The chemical upcycling of ester-based plastics and biomass-derived molecules offers a promising strategy for addressing environmental and ecological challenges. The development of sustainable catalytic processes to convert these abundant feedstocks into value-added chemicals is therefore of great significance. In this study, we introduce a protocol for (EtO)3SiH-mediated, Zr-catalyzed reductive amination, which efficiently converts polyester waste into synthetically valuable amines, amino alcohols, and pyrroles with good yields. Significantly, this method enables the selective valorization of common plastics, including poly(ethylene terephthalate) (PET), polybutylene succinate (PBS), polycaprolactone (PCL), and polylactic acid (PLA), without the undesired reduction of their ester groups to monomeric alcohols. Moreover, this protocol demonstrates broad applicability to biomass-derived esters and lactones, underscoring its potential in converting renewable materials. Importantly, our studies address the essential role of organosilane in use and suggest a dual catalytic cycle, where zirconocene’s Lewis acidity facilitates the aminolysis of polyesters, followed by zirconium hydride catalysis driving the reductive amination of the resulting amides into the target amines. © 2025 American Chemical Society. |
