制备了具有N-苯基取代N-杂环卡宾(NHC)配体的Ru-烯烃歧化反应催化剂，并对其进行了闭环复分解(RCM)、交叉复分解(CM)和ROMP反应。N，N‘-二苯基取代的NHC络合物是催化裂化反应生成四取代烯烃的最有效催化剂之一。
Ruthenium olefin metathesis catalysts bearing an N-phenyl-substituted N-heterocyclic carbene (NHC) ligand that are resistant to decomposition through C-H activation have been prepared and tested in ring closing metathesis (RCM), cross metathesis (CM), and ROMP reactions. The N,N '-diphenyl-substituted NHC complex proved to be one of the most efficient catalysts in RCM to form tetrasubstituted olefins.
