Herein, a metal-free and solvent-free protocol was developed for the C–N coupling of heteroaryl halides and amines, which afforded numerous heteroaryl amines or their hydrochlorides without any external base. Further investigations elucidated that the basicity of amines and specific interactions derived from the X-ray crystallography analysis of 3j′·HCl played pivotal roles in the reactions. Moreover
在此,开发了一种无金属和无溶剂的方案,用于杂芳基卤化物和胺的 C-N 偶联,在没有任何外部碱的情况下提供了许多杂芳基胺或其盐酸盐。进一步的研究表明,胺的碱性和源自3j'·HCl的 X 射线晶体学分析的特定相互作用在反应中起关键作用。此外,该协议可扩展到克级并适用于药物分子,这证明了其进一步应用的实用价值。
