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.
铵盐催化氨基甲酸酯氮加成到非共轭碳 - 碳三键上,生成环状产物。均相体系研究表明,铵试剂通过与炔烃单元的阳离子 - π相互作用促进氮 - 碳键形成,这首次通过拉曼光谱直接观察到。
