Some 4-hydroxy-picolinic acid derived amides were revealed as more efficient ligands for Cu-catalyzed coupling of (hetero)aryl halides with secondary phosphine oxides and phosphites. Only 3—5 mol% CuI and ligands were required to ensure coupling with a number of (hetero)aryl bromides and iodides to complete at 120 oC in 10—20 h.

Cu/Picolinamides-催化的（杂）芳基卤化物与二级氧化膦和亚磷酸盐的偶联†
一些 4-羟基-吡啶甲酸衍生的酰胺被揭示为更有效的配体，用于（杂）芳基卤化物与仲氧化膦和亚磷酸酯的铜催化偶联。仅需要 3-5 mol% CuI 和配体即可确保与许多（杂）芳基溴化物和碘化物的偶联在 120 o C 下在 10-20 小时内完成。
