摘要

发展了钯多相催化剂Pd/MgO （0.5 mol% Pd）参与的芳基羧酸脱羧与卤代芳烃的偶联反应体系. 在与溴代芳烃甚至氯代芳烃的偶联反应中，缺电子和富电子的芳基羧酸均能进行脱羧，并以高收率得到目标产物. 该体系采用的负载型钯多相催化剂制备方法简单易行，可多次循环使用，能便捷地应用于脱羧偶联的有机合成反应.

Abstract

Decarboxylative coupling of arene carboxylic acids with aryl halides is achieved by using a ligand-free Pd/MgO (0.5 mol% Pd) heterogeneous catalyst system. Both electron-rich and electron-deficient arene carboxylic acids can be used as aryl sources to couple a variety of aryl bromides, even aryl chlorides in moderate-to-excellent yields. The establishment of heterogeneous catalysis for the decarboxylative cross-coupling along with the reusability of the heterogeneous catalyst should facilitate the practical application of this transformation in organic synthesis.

Key words： palladium; decarboxylation; carboxylic acid; cross-coupling; heterogeneous catalysis
