carbene

Ring closing metathesis (RCM) of dienes to cycloalkene provides an important tool for C-C double bond formation catalyzed by metal carbene.

关环转换反应是形成碳碳键的重要反应之,烯合物在金属碳烯下关环得到环烯类合物。

Moreover, we found that N-heterocyclic carbene (NHC) could served as an efficient and novel catalyst for the reactions of aziridines with silylated nucleophiles or acid anhydrides.

后，我们发现氮杂环卡宾也可以作为种有机小分子，分别各类硅试或酸酐对氮杂环丙烷合物的开环。
