氨基甲酸酯氮在非共轭碳-碳三键上的加成由铵盐催化生成环状产物。在均相体系中的研究表明，铵剂通过与炔单元的阳离子-π相互作用促进氮碳键的形成，这是第一次用拉曼光谱直接观察到。
The addition of carbamate nitrogen to a non-conjugated carbon-carbon triple bond is catalyzed by an ammonium salt leading to a cyclic product. Studies in homogeneous systems suggest that the ammonium agent facilitates nitrogen-carbon bond formation through a cation-π interaction with the alkyne unit that, for the first time, is directly observed by Raman spectroscopy.
