摘要

在这里，我们报道了碳负载的ni纳米颗粒作为可重复使用的催化剂，用于硝基化合物与聚乳酸（PLA）的还原性酰胺化。通过在碳载体上合成镍-二胺配体，在氩气条件下热解制备纳米镍基催化剂。应用一种最佳的镍纳米结构催化剂，在分子氢的存在下，用不同的硝基化合物对聚乳酸进行酰胺化，得到酰胺产物。在提高反应效率方面，H2O在PLA水解生产乳酸单体过程中起到了积极的作用。同时，由于缺少对乳酸单体形成至关重要的H原子，D2O不能促进PLA水解。

Reductive amidation of polylactic acid with nitro compounds using nickel based nanocatalysts†

Here, we report carbon-supported Ni-nanoparticles as reusable catalysts for reductive amidation of nitro compounds with polylactic acid (PLA). These Ni-nanoparticle-based catalysts are prepared by synthesizing nickel-diamine ligands on a carbon support and subsequent pyrolysis under argon. Applying an optimal Ni-nanostructured catalyst, amidation of PLA with different nitro compounds in the presence of molecular hydrogen was performed to access amide products. Regarding improving the reaction efficiency, H₂O plays a positive role in the PLA hydrolysis process for lactic acid monomer production. Meanwhile, D₂O cannot promote PLA hydrolysis due to the lack of H atoms, which is vital for forming lactic acid monomers.

期刊介绍： Green Chemistry is a journal that provides a unique forum for the publication of innovative research on the development of alternative green and sustainable technologies. The scope of Green Chemistry is based on the definition proposed by Anastas and Warner (Green Chemistry: Theory and Practice, P T Anastas and J C Warner, Oxford University Press, Oxford, 1998), which defines green chemistry as the utilisation of a set of principles that reduces or eliminates the use or generation of hazardous substances in the design, manufacture and application of chemical products. Green Chemistry aims to reduce the environmental impact of the chemical enterprise by developing a technology base that is inherently non-toxic to living things and the environment. The journal welcomes submissions on all aspects of research relating to this endeavor and publishes original and significant cutting-edge research that is likely to be of wide general appeal. For a work to be published, it must present a significant advance in green chemistry, including a comparison with existing methods and a demonstration of advantages over those methods.
