The synthesis of the first four-membered N-heterocyclic carbene is described. Depending on the substituents on the nitrogen atoms, it is possible to characterize at room temperature the carbene dimer or the free carbene. Crystallographic analyses are provided for these carbene species.
本文描述了首个四元氮杂环卡宾的合成。根据氮原子上的取代基,在室温下有可能对卡宾二聚体或游离卡宾进行表征。文中给出了这些卡宾物种的晶体学分析。
