Abstract An amide-assisted arene nitration is presented, and both mono- and dinitration of protected anilines could be effected by using NaNO2 and NaNO3 as the mono- and bisnitrating agents, respectively. This divergent synthesis is transition-metal- and acid-free, and features a broad substrate scope, low cost, and ortho–para selectivity. Graphical Abstract
摘要 提出了酰胺辅助芳烃硝化,分别使用NaNO2和NaNO3作为单硝化剂和双硝化剂,可以实现受保护苯胺的单硝化和二硝化。这种发散合成不含过渡金属和酸,具有广泛的底物范围、低成本和邻位选择性。图形概要
