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.

随后，我们发现氮卡宾也可以作为一种有机催化剂，别催化各硅试剂或酸酐对氮烷化合物的开。

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

关转换反应是形成碳碳双键的重要反应之一,即双烯化合物在金属碳烯催化下关得到烯化合物。
