Carbodicarbenes activate N₂O in a NHC/N₂ ligand exchange reaction to give stable diazoalkenes and a urea byproduct. By applying the NHC/N₂ exchange, new classes of benzimidazole- and benzothiazole-diazoalkenes are reported. Combining two-fold ligand exchange reactions at C(0) a versatile route to carbodicarbenes and cumulenes is opened up.

碳二卡宾与 N2O 的裂解以获得稳定的重氮碳烯烃：在 c（0）-原子处的两重配体交换

碳二卡宾在 NHC/N₂ 配体交换反应中激活 N₂O，得到稳定的重氮烯烃和尿素副产物。通过应用 NHC/N₂ 交换，报道了新类别的苯并咪唑 - 和苯并噻唑 - 重氮烯烃。在 C（0）处结合双重配体交换反应，开辟了通往碳二卡宾和倭维烯的通用途径。
