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重要反应之一,即烯化合物在金属碳烯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.

随后，我们发环卡宾也可以作为一种有机小分子化剂，分别化各类硅试剂或酸酐对环丙烷化合物开环。
