摘要

向可持续的、碳中和的生物炼制推进已经成为现代科学和工程努力的核心目标。随着石油资源的日益稀缺，生物质衍生碳作为生产燃料和工业化学品的替代品已经出现。在未充分利用的生物材料中，木质素脱颖而出——但其复杂的、交联的和不规则的聚合物结构使其抵抗传统的化学处理。金属有机配合物催化木质素解聚的新进展由于其高催化效率而引起了人们的新兴趣。本文综述了催化木质素单体、木质素二聚体模型化合物和金属有机配合物催化的木质素原料，并简要介绍了以木质素转化为高价值产品为目标的木质素领域的研究进展。对这些反应的机理提出了建议，以进一步举例说明这些过程。

Organometallic catalysts for lignin depolymerization

Advancing towards sustainable, carbon-neutral biorefineries has risen as a central ambition in modern scientific and engineering efforts. With petroleum resources becoming increasingly scarce, biomass-derived carbon as an alternative for producing fuels and industrial chemicals has emerged. Among underused biomaterials, lignin stands out—yet its complex, crosslinked, and irregular polymeric structure has made it resistant to conventional chemical processing. Recent advances in the depolymerization of lignin catalyzed by organometallic complexes have attracted renewed interest owing to their high catalytic efficiency. This review aims at illustrating catalytic lignin monomer, lignin dimer model compounds and lignin feedstocks catalyzed by organometallic complexes and gives a concise account of achievements in the field with the aim of transforming lignin into high-value products. Proposals for the mechanism of these reactions are provided to further exemplify the processes.

期刊介绍： The Journal of Organometallic Chemistry targets original papers dealing with theoretical aspects, structural chemistry, synthesis, physical and chemical properties (including reaction mechanisms), and practical applications of organometallic compounds. Organometallic compounds are defined as compounds that contain metal - carbon bonds. The term metal includes all alkali and alkaline earth metals, all transition metals and the lanthanides and actinides in the Periodic Table. Metalloids including the elements in Group 13 and the heavier members of the Groups 14 - 16 are also included. The term chemistry includes syntheses, characterizations and reaction chemistry of all such compounds. Research reports based on use of organometallic complexes in bioorganometallic chemistry, medicine, material sciences, homogeneous catalysis and energy conversion are also welcome. The scope of the journal has been enlarged to encompass important research on organometallic complexes in bioorganometallic chemistry and material sciences, and of heavier main group elements in organometallic chemistry. The journal also publishes review articles, short communications and notes.
