研制了含2，3，4，5-四苯基苯基N-杂环卡宾配体(1-TPPh和1-TPPh*)的Ru基异构化催化剂。以1-TPPh*和CuCl2为膦清除剂，在四氢呋喃中实现了高活性催化体系。
Ruthenium-based metathesis catalysts with a N-heterocyclic carbene ligand bearing 2,3,4,5-tetraphenylphenyl moieties (1-TPPh and 1-TPPh*) are developed. The highly active catalyst system has been realized in THF by the combination of 1-TPPh* and CuCl as a phosphine scavenger.
