介绍了以氟化NHC为配体的新型钌基烯烃复分解催化剂的合成、结构和性能。将卤素原子引入到n -杂环碳配体中，大大改变了催化活性，可以提供更高效的催化剂。结构研究表明，氟-钌相互作用是这种活性增加的原因。
The synthesis, structure, and performance of new ruthenium-based olefin metathesis catalysts, featuring fluorinated NHC ligands are presented. The introduction of halogen atoms into the N-heterocyclic carbene ligand profoundly alters the catalytic activity and can afford a more efficient catalyst. Structural investigations suggest that a fluorine-ruthenium interaction is responsible for this increased activity.
