efficient palladium‐catalyzed chlorocarbonylation of aryl (pseudo)halides that gives access to a wide range of carboxylic acid derivatives has been developed. The use of butyryl chloride as a combined CO and Cl source eludes the need for toxic, gaseous carbon monoxide, thus facilitating the synthesis of high‐value products from readily available aryl (pseudo)halides. The combination of palladium(0), Xantphos
已经开发了一种有效的钯催化的芳基(假)卤化物的氯羰基化反应,该反应可以使用多种羧酸衍生物。使用丁酰氯作为CO和Cl的混合来源,就不需要有毒的气态一氧化碳,从而促进了从容易获得的芳基(伪)卤化物合成高价值产品的需求。钯(0),黄药和胺碱的组合对于促进这种广泛适用的催化反应至关重要。总体而言,该反应可通过原位生成的芳酰氯的转化获得多种含羰基的产物。结合实验和计算研究,可以支持涉及原位生成CO的反应机理。
