Lignin chemistry is regarded as one of the core components in the field of biomass catalytic conversion. Over the past decade, the catalytic synthesis of value-added chemicals or biofuels via oxidation/reduction depolymerization with lignin as the initial substrate has made extensive progress through ongoing research attempts. However, there are fewer investigations on the conversion of lignin derivatives to nitrogen-containing compounds such as aniline and benzylamine through heterogeneous catalytic amination. On this account, this paper reviews the amination value-added reaction processes of lignin-derived phenols, ethers, carbonyl compounds and alcohols to produce aniline and benzylamine, mainly focusing on cheap catalysts, green solvent systems, nitrogen source systems, and mild reaction conditions, which can provide novel perspectives to promote the processive innovation of a sustainable lignin amination system. The perspectives on the synthesis of lignin-based aniline and benzylamine proposed in this review are intended to offer novel research ideas for further expanding the boundaries of the biomass refining systems involving lignin amination chemistry.

木质素胺化价值化：从木质素衍生的化学品中多相催化合成苯胺和苄胺

木质素化学被认为是生物质催化转化领域的核心组成部分之一。在过去的十年中，增值化学品或生物燃料的催化合成通过通过正在进行的研究尝试，以木质素为初始底物的氧化/还原解聚已经取得了广泛的进展。然而，关于通过多相催化胺化将木质素衍生物转化为含氮化合物如苯胺和苄胺的研究较少。为此，本文综述了木质素衍生的酚类、醚类、羰基化合物和醇类制备苯胺和苄胺的胺化增值反应过程，主要侧重于廉价催化剂、绿色溶剂体系、氮源体系和温和的反应条件。 ，这可以为促进可持续木质素胺化系统的不断创新提供新的视角。
