A practical copper‐catalyzed direct nitration of protected anilines, by using one equivalent of nitric acid as the nitrating agent, has been developed. This procedure features mild reaction conditions, wide structural scope (with regard to both N‐protecting group and arene substitution), and high functional‐group tolerance. Dinitration with two equivalents of nitric acid is also feasible.
通过使用一当量的硝酸作为硝化剂,已开发出一种实用的铜催化的被保护的苯胺直接硝化方法。该程序的特点是反应条件温和,结构范围广(就N保护基和芳烃取代而言)以及高官能团耐受性。用两当量的硝酸进行消解也是可行的。
