Coupling reactions of α-chloroesters with aryl halides (α-arylation) or carbonyl compounds (Reformatsky) using nickel catalyst allow, under mild conditions, the preparation of various functionalized aryl propionic acid derivatives or β-hydroxyesters. In the synthesis of aryl propionic acid derivatives, the process is efficient with aryl halides bearing either electron-withdrawing or electron-donating
使用镍催化剂,α-氯酸酯与芳基卤化物(α-芳基化)或羰基化合物(Reformatsky)的偶联反应可以在温和的条件下制备各种官能化的芳基丙酸衍生物或β-羟基酯。在芳基丙酸衍生物的合成中,该方法对于带有带吸电子基团或给电子基团的芳基卤化物是有效的。
