[10% Cu(NO3)(2)3H(2)O] nitration of anilides was developed by using TBN (tert-butyl nitrite) as a nitrating reagent to give the corresponding nitro-substituted aromatic products in good to excellent yields. The use of TBN also led to the selective nitration of acrylamides at room temperature to afford only the (E) isomer of the nitration product. A series of anilides and acrylamides with a broad array
硝基化合物是合成有机化学和化学工业中的重要中间体。在此,以TBN(亚硝酸叔丁酯)为硝化试剂,开发了铜催化[10% Cu(NO3)(2)3H(2)O]硝化苯胺的高效硝化反应,得到相应的硝基取代芳烃产物。良好的产量。TBN 的使用还导致丙烯酰胺在室温下选择性硝化以仅提供硝化产物的 (E) 异构体。该程序对一系列具有广泛官能团的苯胺和丙烯酰胺具有良好的耐受性。该合成方法具有原料廉价、反应条件温和、反应速度快、收率高等优点。机理研究表明,一个硝基自由基,
