carbene

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

关环转换形成碳碳双键的重要之一,即双烯化合物在金属碳烯催化下关环得到环烯类化合物。

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，我们发现环卡宾也可以作为一种有机小分子催化剂，分别催化各类硅试剂或酸酐环丙烷化合物的开环。
