  DOI：10.1002/ejoc.201200989

  日期：2012.12

  olefin metathesis catalyst was prepared through the incorporation of a chelated pyrimidinyl methylene subunit, in which electron-rich substituents were attached to stabilize the ruthenium complexes. These catalysts were successfully used in various types of olefin metathesis reactions, including ring-closing metathesis (RCM), cross-metathesis (CM), enyne metathesis (EM), and ring-opening metathesis polymerization

  通过引入螯合的嘧啶基亚甲基亚单元制备了一种新型的N-杂环卡宾载钌烯烃复分解催化剂，其中富电子取代基被连接以稳定钌配合物。这些催化剂已成功用于各种类型的烯烃复分解反应，包括闭环复分解（RCM）、交叉复分解（CM）、烯炔复分解（EM）和开环复分解聚合（ROMP）反应。其中的结果表明，缺电子嘧啶结构的存在大大增强了新的 NHC 钌配合物的催化活性。
