hydrocarbon solvents (principally CH2Cl2) to give vicinal nitrate ester products by a novel ring-opening nitration reaction. The procedure offers easier temperature control and simpler isolation procedures compared with conventional mixed acid nitrations; it also enables selective nitration reactions to be carried out on polyfunctional substrates. The scope and limitations of the reaction, as well as
通过新颖的开环硝化反应,使十八种各种环氧化合物与N 2 O 5在氯化烃溶剂(主要为CH 2 Cl 2)中反应,得到邻位硝酸酯产物。与传统的混合酸硝化方法相比,该方法提供了更轻松的温度控制和更简单的分离步骤。它还可以在多官能底物上进行选择性硝化反应。讨论了反应的范围和局限性,以及利用N 2 O 4与硝酸亚硝酸酯原位进行原位氧化的替代方法的范围和局限性。
