carbene

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

换反应是形成碳碳双键的重要反应之一,即双烯合物在金属碳烯催下得到烯类合物。

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，我们发现氮杂卡宾也可以作为一种有机小分子催剂，分别催各类硅试剂或酸酐对氮杂合物的开。
