Pd催化(杂环)芳基羧酸脱羧的偶联反应研究进展

Recent Progress in Pd-Catalyzed Decarboxylative Coupling Reactions of(Hetero)aromatic Carboxylic Acids

羧酸具有无毒、廉价易得、稳定易存储等特点,有关过渡金属Pd催化(杂环)芳基羧酸脱羧的偶联反应在本世纪来得到了迅速发展,大有取代传统偶联反应之势.本文综述了Pd催化(杂环)芳基羧酸脱羧与多种底物的偶联反应,如烯、芳基卤化物、芳烃,三氟芳基硼酸盐等底物,并对相关的反应机理进行了探讨.

Since carboxylic acids have distinguishing features of non-toxicity, low cost, ready availability and easy storage, Pd-catalyzed decarboxylative coupling reactions of （hetero）aromatic carboxylic acids have been obtained rapid development since this century, and have exhibited a tendency toward replacement of traditional coupling reactions. The coupling reactions of Pd-catalyzed decarboxylation of aromatic carboxylic acids with various substrates of olefins, aryl halides, arenes, aryltrifluoroborates and etc. are reviewed, and the relevant reaction mechanisms are discussed.
