This review describes a distinct class of ruthenium olefin metathesis catalysts featuring unsymmetrical N-heterocyclic carbene (uNHC) ligands, from its historical beginning to the present state of the art. Thanks to advantageous traits, such as pronounced thermodynamic stability, chemical latency, outstanding selectivity, and compatibility with green solvents, these catalysts led to good results in a number of specialized metathesis transformations. Therefore, while being a niche, the uNHC complexes can potentially be implemented in a number of industrial processes, such as valorization of Fischer-Tropsch olefin fractions, ethenolysis of renewable products, and modern pharmaceutical production.

具有不对称 N-杂环卡宾配体的钌配合物——用于特殊任务的有用的烯烃复分解催化剂

这篇综述描述了一类独特的钌烯烃复分解催化剂，其特征是不对称的 N-杂环卡宾 (uNHC) 配体，从其历史开始到现在的技术水平。由于具有显着的热力学稳定性、化学潜伏期、出色的选择性以及与绿色溶剂的相容性等优势，这些催化剂在许多专门的复分解转化中取得了良好的效果。因此，虽然是一个利基市场，但 uNHC 复合物有可能在许多工业过程中实施，例如费托烯烃馏分的增值、可再生产品的乙烯分解和现代制药生产。
