Diaryliodonium salts are employed to directly quaternize N-substituted imidazoles by using a copper catalyst to construct aryl imidazolium salts in moderate to excellent yields. This transformation is tolerant to a broad range of functional groups and provides a straightforward, efficient, and versatile route to synthesize aryl imidazolium as well as triazolium salts, especially the unsymmetric version.
二芳基碘𬭩盐被用于通过使用铜催化剂直接季铵化 N-取代的咪唑,以中等至优异的产率构建芳基咪唑鎓盐。这种转化对广泛的官能团具有耐受性,并提供了一种直接、高效和通用的方法来合成芳基咪唑鎓盐和三唑鎓盐,特别是不对称版本。
