A simple and practical protodecarboxylation of o-nitrobenzoic acids as well as heteroaromatic carboxylic acids with various substituents via using CuI/Et3N has been established. This transformation provides a viable and low-cost approach to generating previously unavailable substituted arenes from readily accessible aryl carboxylic acids as the starting materials.
通过使用CuI / Et 3 N,已经建立了具有各种取代基的邻硝基苯甲酸以及杂芳族羧酸的简单而实用的原脱羧。这种转化提供了一种可行且低成本的方法,该方法可从易获得的芳基羧酸作为起始原料生成先前不可用的取代芳烃。
Silver-Catalyzed Protodecarboxylation of Heteroaromatic Carboxylic Acids
A simple and highly efficient protodecarboxylation procedure for a variety of heteroaromatic carboxylic acids catalyzed by Ag2CO3 and AcOH in DMSO is described. This methodology can also perform the selective monoprotodecarboxylation of several aromatic dicarboxylic acids.
描述了在DMSO中由Ag 2 CO 3和AcOH催化的多种杂芳族羧酸的简单高效的原脱羧过程。该方法学还可以进行几种芳族二羧酸的选择性单原羧化。

A variety of hetero(aromatic) carboxylicacids are shown to undergo decarboxylative homocoupling, mediated by a Pd/Ag system. This novel methodology for the synthesis of symmetrical biaryls avoids the use of haloarenes and organometallic compounds as starting materials.
