The CuI/l-proline sodium salt catalyzed coupling reaction of arylhalides with sulfinic acid salts readily occurs at 80−95 °C in DMSO to give the corresponding aryl sulfones in good to excellent yields. This process is well-tolerated by a wide range of functional groups including hydroxyl, amino, acetanilide, ketone, ester, and nitrile. Using this method, 4-phenylsulfonyl- and 4-methanesulfonyl-substituted
CuI / 1-脯氨酸钠盐催化的芳基卤化物与亚磺酸盐的偶联反应在DMSO中于80-95°C容易发生,从而以良好或极好的收率得到相应的芳基砜。广泛的官能团(包括羟基,氨基,乙酰苯胺,酮,酯和腈)可以很好地耐受该过程。使用这种方法,制备了4-苯基磺酰基-和4-甲磺酰基取代的1-苯基丙氨酸衍生物。
