Various nitro azaheterocyclic compounds were subjected to C–H amination by vicariousnucleophilic substitution with 4H-1,2,4-triazol-4-amine (ATA). The aminated products were characterized by NMR, mass spectroscopy, and single-crystal X-ray diffraction analyses. The substrates examined gave moderate to excellent yields (30–88%) and showed good regioselectivities. This protocol offers the advantages
各种硝基氮杂杂环化合物通过与 4H-1,2,4-三唑-4-胺 (ATA) 的替代亲核取代进行 C-H 胺化。胺化产物通过核磁共振、质谱和单晶 X 射线衍射分析进行表征。检查的底物具有中等至极好的产率(30-88%),并显示出良好的区域选择性。该方案具有条件温和、反应时间短(2-4 小时)以及廉价、市售且毒性较低的胺化试剂等优点;此外,不需要额外的催化剂或试剂。讨论了可能的反应机理。
