The amide derived from 4-hydroxy-l-proline and 2,6-dimethylaniline is a powerful ligand for Cu-catalyzed coupling of (hetero)aryl halides with sulfinic acid salts, allowing the formation of a wide range of (hetero)aryl sulfones from the corresponding (hetero)aryl halides at considerably low catalytic loadings. The coupling of (hetero)aryl iodides and sodium methanesulfinate proceeds at room temperature
衍生自4-羟基-1-脯氨酸和2,6-二甲基苯胺的酰胺是Cu催化(杂)芳基卤化物与亚磺酸盐偶联的强配体,可形成各种(杂)芳基砜由相应的(杂)芳基卤化物以低的催化负载量得到。(杂)芳基碘化物和甲烷亚磺酸钠的偶联在室温下仅用0.5mol%的CuI和配体进行,代表了在低催化负载和室温下Cu催化的芳基化的第一个实例。
