摘要
研究了二氯二(三来膦)钯催化下及聚乙二醇存在下劳卤与二氧化碳的羰基化反应,提供了芳香族羰酸的简便合成法.本法优点是反应条件温和,反应在常压下进行;对多卤化物有良好的化学选择性,芳碘优先发生羰基化而分子中的氯和滇原子不受影响。
Dichloro-bis (triphenyl-phosphine) palladium catalyzed carbonylation of aryl halides with carbon monox-
ide in the presence of PEG is studied and a new convenient method for the synthesis of aromatic acids is af-
forded. The advantages of this method are mild conditions, such as the reaction can be carried out at normal
pressure, and excellent selectivity for polyhalides, such as aryl iodide can be carbonylated without influence
of chlorine and bromine atom.
